Subject:Report on the Fixed Link to the City Centre Airport Environmental Assessment (Downtown)
Purpose:
To inform City Council of the findings of the Federal Environmental Assessment concerning the fixed link (bridge)
to the City Centre Airport (airport) and recommend, provided the Environmental Assessment is approved by
federal authorities, design and operational requirements for both the bridge and Bathurst Street, new terms and
conditions which should be added to the Tripartite Agreement as a condition of City Council agreeing to the
construction of the bridge and to an exchange of land between the City and the federal government which will
result in additional park space.
Source of Funds:
There are no funding requirements arising from the recommendations of this report.
Recommendations:
(1)That City Council authorize amendments to the Tripartite Agreement, including those set out in
Recommendation No. (2), to permit a bridge to the airport, subject to the approval of the Environmental
Assessment and subject to The Toronto Harbour Commissioners completing the following to ensure that they are
included in the design and construction program of the bridge:
(a)the bridge contain only two lanes of vehicular traffic each having a width of no more than 3.5 metres;
(b)sidewalks, having a width of 2.0 metres, be provided on both sides of the bridge structure and on the
approaches to the bridge;

(ii)when airport-bound vehicular traffic reaches a peak volume of 100 vehicles per hour as measured along
Bathurst Street south of Queen's Quay;
(d)that The Toronto Harbour Commissioners be required to monitor the effects of the bridge operation, as
requested by the City, on:
-traffic volumes inbound and outbound on the bridge;
-use of the parking facility;
-extent of the queues on Bathurst Street;

the bridge to the City, to be dedicated as a public highway;
(4)that the City be released and discharged from any obligations to The Toronto Harbour Commissioners to
provide parking facilities in relation to airport parking on Bathurst Quay, as required by the agreements entered
into between the City and The Toronto Harbour Commissioners and any license agreement arising out of same,
including the interim parking arrangements on Bathurst Quay 5;
(5)that all rights to land held by the Federal Government, and currently used for public parking at the end of
Bathurst Street and the ferry slip and access road leading to it, be conveyed to the City at nominal cost for public
park and public highway purposes;
(6)that the 100 foot wide access easement located immediately adjacent to the Bathurst Street road allowance,
granted in favour of the Federal Government for the purposes of ensuring future access to the airport, be released
from title at the time the Tripartite Agreement is amended to permit the use of the bridge; and
(7)that the Commissioner of Urban Planning and Development Services, together with other appropriate City
officials, report on other measures which should be included as conditions in the Tripartite Agreement that address
the cumulative impacts resulting from the introduction of a bridge and all Stage 3 turbo-prop aircraft at the airport,
when appropriate.
1. Introduction and Background
The former City of Toronto Council, at its meeting held on October 16 and 17, 1995, endorsed building a fixed link
to the City Centre Airport subject to the completion of an Environmental Assessment. At its meeting held on
August 21, 1997, City Council requested the Minister of Transport to undertake a full Environmental Assessment
for the fixed link proposal to the City Centre Airport because of public concerns and significant adverse
environmental effects despite proposed mitigation measures. In addition, City Council requested a report on the
then Draft Environmental Assessment document.
In two previous reports dated February 27, 1997 and June 12, 1997, it was recommended that, further to the former
City Council=s October 15 and 16, 1995 motion to support a fixed link, Council support a moveable, two lane
bridge option subject to several conditions which ensure the design takes into account City objectives for this part
of the waterfront. In addition, staff recommended that other related matters such as selecting a new parking
location, limiting the amount of parking, encouraging the use of public transit, regulating vehicle access to the City
Centre Airport, and studying and constructing a remote (off-site) terminal concept, be secured through amendments
to the Tripartite Agreement as a condition of City Council=s acceptance of the bridge. The Tripartite Agreement is
a lease agreement between the City, the Toronto Harbour Commissioners and the federal government, entered into
1983, whereby the City has agreed to lease a finger-shaped portion of land in the middle of the airport for airport
purposes subject to certain terms and conditions governing the operation of the airport.
Recently, the Environmental Assessment of the fixed link proposal was submitted to federal authorities. The EA
report concludes that it is unlikely that the proposed construction and operation of a moveable bridge at the foot of
Bathurst Street will cause any significant adverse environmental effects. Copies of the document were place in the
Toronto Harbour Commissioners archives and at the Harbourfront Community Centre. Notifications indicating the
availability of the document went to all individuals and organizations on the mailing list.
If members of the public are of the view that the proposed project will cause significant adverse environmental
effects despite the mitigation measures proposed by the EA document, they may request the Minister of Transport
to refer the matter to Panel Review which involves a second and usually more arduous examination of the proposal.
This report is not recommending such action because for a bridge to be constructed to the airport will require an
amendment to the Tripartite Agreement. In amending the Tripartite Agreement to permit the proposed bridge, the
City can secure provisions which would mitigate the concerns resulting from the construction of the bridge.
The Environmental Assessment report was circulated for comments to appropriate staff in Works and Emergency
Services, Corporate Services, including the City Solicitor, and Community Services.
2.The Environmental Assessment Report
2.1Content of Report
The conclusions found in the Fixed Link to the City Centre Airport Environmental Assessment report remain the
same as have been presented to the former City Council in previous reports with the exception of Appendix A.
Appendix A, titled Additional Matters, discusses the potential impacts associated with an increase in air traffic. The
Additional Matters contained in Appendix A do not form part of the Environmental Assessment and consequently
are not subject to review through that process. However, the City can recommend the addition of new terms and
conditions to the Tripartite Agreement to the City=s concerns related to overall impact of any increased air traffic
resulting from the construction of the bridge. For this reason, it recommended that staff report further on possible
measures for mitigating potential impacts resulting from increased air traffic.
The remainder of this section examines the key issues arising from the conclusions of the Environmental
Assessment report and outlines the requirements of City Council related to bridge design, road improvements and
other matters should the Environmental Assessment for the Fixed Link be approved.
2.2Project Definition
Previous reports and documents had not specified the scope of the project insofar as construction activities were
concerned. The draft Environmental Assessment report lists the activities associated with the construction of the
bridge as including:
-constructing the piers and control tower (if needed)
-assembling the bridge superstructure
-demolishing two hangars (1 & 2) at the airport
-constructing the roadway approaches to the bridge including alterations to Bathurst Street
-constructing the parking lot at the airport
-filling in the ferry slips
-landscaping along all edges of the project area
The construction of the parking facility is a significant feature of the project. The Environmental Assessment report
indicates that 173 surface parking spaces are proposed on the airport site in the location of hangars 1 and 2. This is
a prominent location along the City=s waterfront and appropriate landscaping is important. The detailed
landscaping plans should be reviewed by City staff prior to implementation.
2.3Bridge Design
The Environmental Assessment report describes the project as a double bascule (draw) bridge at the foot of
Bathurst Street. The underside of the bridge would be 5 metres above the average high water level and the
moveable spans of the bridge would provide an opening of 50 metres in width located in the centre of the Western
Channel. There are two options proposed for the bridge deck. One alternative proposes at 13 metre wide structure
providing for two lanes of traffic at 3.75 metres in width, two shoulders 0.5 metres wide and two sidewalks each
2.25 metres wide. The second alternative design proposes a deck 14.5 metres wide consisting of two vehicular
lanes 3.5 metres wide, two bike lanes at 1.5 metres in width and two sidewalks at 2.25 metres in width each. At
previous Committee meetings of the former City Council, concerns were raised with respect to the overall size of
the structure. In order to minimize the width of the bridge deck, staff are recommending that the maximum
vehicular lanes widths be 3.5 metres. However, two sidewalks should be provided for safety reasons at a minimum
2.0 metres. It also recommended that the Toronto Harbour Commissioners seek the input of the community and
staff on various optional designs prior to selecting a final design.
In a report dated June 12, 1997, staff recommended that bicycle lanes be introduced along Bathurst Street and over
the bridge. At the Executive Committee meeting of the former City, held on August 15, 1997, comments from
Committee members and the public questioned the need for bicycle lanes to the airport, especially in relation to
another objective which is to reduce the width of the road pavement south of Queens Quay given the predominance
of park and recreation uses in the area. The Environmental Assessment report proposed the bicycle lanes as an
option which can be accommodated into the design. However, given the concern with the road pavement width,
bicycle lanes should not be required.
The width of the water=s edge promenade running beneath the bridge is proposed at a width of 6 metres. However,
the current width of the water=s edge promenade throughout Harbourfront is 7 metres. A consistent width of 7
metres should be maintained.
The Canada Malting site has two existing driveways. However, the most southerly driveway has been the historical
main entrance to the site and should be retained. City Works staff believe it is possible to retain access at this
location although the vertical alignment of the driveway would have to modified as a result of the grade or bridge
approaches. The Environmental Assessment document does indicate two entrances can be accommodated.
2.4Bridge Operating Procedures
The Environmental Assessment report proposes a fixed operating schedule whereby the bridge would open twice
an hour. The length of time the bridge would remain open will be entirely dependent on the time of day.
Consequently, the bridge may remain open as long as 16 minutes during airport non peak hours and during peak
periods the bridge would remain open for 7 minutes. According to the report, peak periods would occur for a two
and a half hour period in the morning, a two hour period at noon, and a two and a half hour period in the evening.
The bridge cycle time would consist of:
traffic control |
0.75 min. |
bridge unlocking |
0.5 min |
bridge opening |
1.0 min. |
boat passage |
7.0 min. - 16 min. |
bridge closure |
1.0 min. |
locking |
0.5 min |
traffic control |
0.25 min |
Total |
11.0 min. - 20 min. |
The effect of the operation of the bridge in terms of its cycles of opening and closing on traffic along Bathurst
Street has been studied by the consultant. A Transportation Evaluation is included in Appendix B of the
Environmental Assessment report. Works and Emergency Services staff have reviewed the evaluation and concur
with the consultant=s conclusion that the traffic generated by this proposal can be safely and effectively
accommodated on Bathurst Street and the abutting intersections with the proposed modifications to the facilities.
However, when airport bound traffic reaches a level of more than 100 vehicles an hour and the bridge is opened,
the Environmental Assessment report indicates that Aeither a southbound queuing lane will need to be constructed,
or passengers will have to be handled through a remote terminal.@ This level of traffic is expected to occur in the
late afternoon rush hour during the busiest of weekdays. Bathurst Street can accommodate approximately 20
queued vehicles without hindering other traffic.
Initially, it was suggested that an additional southbound lane be added to Bathurst Street to permit the queuing of
vehicles during peak periods. However, in an earlier report dated June 12, 1997, it was recommended that the
queuing lane be eliminated in favour of strategies to reduce the number of vehicles travelling to the airport
(discussed further in Section 3 of this report). These strategies might include more shuttle bus service or public
transit use and the development of a remote (off-site) terminal sooner. It is recommended that the development of
these strategies be incorporated as requirements within the Tripartite Agreement.
Works and Emergency Services staff indicate that, given the importance of the bridge operation on traffic in the
area, a key component of impact assessment is ongoing monitoring of bridge operation. Once the bridge is
operational, the Toronto Harbour Commissioners should be required to monitor: -traffic volumes inbound and outbound on the bridge
-use of the parking facility
-extent of the queues on Bathurst Street
-operations at the Bathurst Street/Queens Quay intersection
-impact on access to the abutting properties
-effectiveness of any traffic calming measures implemented
-conflicts between airport-related traffic and other vehicular and pedestrian activity on Bathurst Street
The results of the monitoring exercise should be reviewed to determine the need for change to the timing of the
bridge operations or the access control.
It is recommended that the requirements for monitoring and review of the results be secured through conditions in
the Tripartite Agreement.
2.5Bathurst Street Alterations
The Environmental Assessment report illustrates possible alterations to Bathurst Street in the form of pavement
widening, the construction of sidewalks, line painting, the installation of gates and signals and the installation of
Atraffic calming@ devices form part of the project work. In Figure 2.1 of the Environmental Assessment report,
Bathurst Street is depicted as a two lane road, each lane being 3.5 metres wide, and centre turn lane also 3.5 metres
wide. Two bicycle lanes, each 1.5 metres in width, are shown together with two sidewalks each 1.5 metres wide.
The total width of the road pavement under this proposal would be 13.5 metres.
As mentioned above, comments made at the Executive Committee meeting of the former City, held on August 15,
1997 questioned the need for bicycle lanes along Bathurst Street to the airport especially when considering the
objective of reducing the overall pavement proposed for the altered Bathurst Street. As a result, alternative designs
should be presented by the Toronto Harbour Commissioners that would reduce pavement width of Bathurst Street.
In addition, the west side of Bathurst, the sidewalk should be 3 metres wide, in keeping with Harbourfront sidewalk
widths, and a landscape zone 2 metres wide. On the east side of Bathurst Street a 2 metre wide sidewalk is under
construction and should be extended together with a 2.5 metre landscape zone. The detailed design of Bathurst
Street, as altered, together with road pavement layout, sidewalks, landscaping, and traffic calming measures should
be submitted to the City prior to any construction.
In addition to physical improvements to Bathurst Street, the City Solicitor indicates that the area of land south of
the existing Bathurst Street road allowance would have to be dedicated as a public highway. Currently the road
allowance ends at the entrance to the ferry area.
3.Amendments to the Tripartite Agreement
City Council=s endorsement of the construction of the fixed link proposal in October 1995 was conditional upon
amendments to the Tripartite Agreement being enacted to ensure that any adverse effects arising from introduction
of a fixed link in combination with the introduction of Stage 3 turbo-prop aircraft could be controlled to a level
acceptable to the City. Below are described the mitigating measures which could be introduced as conditions in the
Tripartite Agreement. The Tripartite Agreement is used in this manner because airports are regulated by federal
legislation and the City has no control over matters of federal jurisdiction. The City of Toronto is the only city in
Canada with such an agreement.
(a)Develop strategies encouraging public transit access to the airport
With increased use of the airport by passenger aircraft, vehicle movements to the airport would likely also increase.
The Environmental Assessment consultant predicts that when the airport reaches 600,000 passengers per annum
there will be a need for an additional traffic lane to accommodate vehicles forming a queue when the bridge is
raised during peak hour, likely sometime between the hours of 4 to 6 p.m. on Thursday or Friday afternoons in the
summer months. Encouraging the use of a regular shuttle bus service between the downtown (Union Station) and
the airport would assist in reducing the number of vehicles going to and from the airport. Private automobiles
pick-ups should also be discouraged at all times, especially since a shuttle bus service could connect passengers
with the City=s transit system and taxi service and major hotels in the downtown area.
(b)Remove all parking spaces associated with the airport on Bathurst Quay
By moving the existing parking found on Bathurst Quay to the airport lands, approximately one and half acres
could be made available for park purposes on Bathurst Quay.
(c)Limit the total number of parking spaces on the airport lands to 400 spaces
There currently exists 208 parking spaces associated with the airport on Bathurst Quay. There are an additional 100
spaces located on the airport lands. The Harbourfront Official Plan and Zoning By-law permits 400 spaces to be
located on Bathurst Quay, south of Queens Quay. It is recommended that the 400 parking spaces permitted by the
Official Plan and Zoning By-law be transferred to the airport lands. This amount of 400 spaces is 92 spaces more
than currently exists. This is a reasonable figure given that there will likely be an increase in use by air passengers.
However, since the long term objective is to construct a remote terminal somewhere in the downtown area, the
demand for parking at the airport could decrease. The Toronto Harbour Commissioners should also develop a
strategy to encourage public transit use. In addition, building and landscaping plans associated with the
construction of a parking facility, at grade or in a structure, should be submitted to the City for review prior to any
construction.
(d)Require the construction of a remote terminal
Construction of a remote (off-site) terminal will likely only occur when passenger loads warrant the cost involved.
The Toronto Harbour Commissioners should study this concept now and construct such a terminal when sustained
passenger loads warrant. The Tripartite Agreement should be amended to require that a remote terminal must be
operational at a sustained annual passenger volume to be agreed upon with the City but at no greater an amount
than 600,000 annual passengers or if airport bound traffic begins to exceed a rate of 100 vehicles an hour.
4.Transfer of Lands on Bathurst Quay to the City
There are several parcels of land on Bathurst Quay which are associated with airport use (see Map 1). The existing
parking lot at the end of Bathurst Street and the access area around the ferry slip is owned by the federal
government. This land should be transferred to the City. The Aorange lands@, located on the east side of Bathurst
Street, are owned by the City but are referenced in certain agreements as a potential permanent parking site for the
airport. These arrangements should also be rescinded. To the west of the Bathurst Street road allowance is a one
hundred foot wide right-of-way in favour of the Crown held for the purposes of securing a access route to the
airport should Bathurst Street be closed. This federal easement should be released once the Tripartite Agreement
has been approved. Contact Name:Joe D=Abramo
