Redway Road and Brentcliffe Road Extensions

Feasibility Study


The purpose of this study is to determine the need and feasibility of extending Redway Road westerly from its current terminus to Bayview Avenue and the extension of Brentcliffe Road southerly from Wicksteed Avenue to Millwood Road on the south side of the CPR Mid-Toronto Subdivision. These two roads have previously been considered as separate projects, however, given the potential connection of these two links and the impact on the surrounding neighbourhoods, they are being considered collectively for the purposes of this study. The background of these two road extensions is given below.

Redway Road Extension

Former Borough of East York Council, at its meeting on September 16, 1996, recommended that a study be conducted to investigate completing the connection of Redway Road with Bayview Avenue. This extension was proposed as a potential means of reducing traffic volume through the South Leaside area in the East York District. The lack of an arterial connection between Bayview Avenue and Laird Drive, south of Eglinton Avenue, has resulted in non-local motorists using South Leaside streets such as Southvale Drive as an alternate. Southvale Drive currently carries approximately 15,000 vehicles on a daily basis with the majority of these motorists originating outside of the Leaside area. Although defined as a collector road in the East York Official Plan, the current traffic volumes are more characteristic of an arterial road. The existing traffic volumes, in conjunction with potential future increases resulting from numerous large scale developments being planned in the area, have resulted in requests to review extending Redway Road to Bayview Avenue to act as a bypass to South Leaside streets.

Redway Road currently serves as an access to a Loblaws Store and to the North Toronto Sewage Treatment Plant.

Brentcliffe Road Extension

The South Leaside industrial area, located in the southeast quadrant of Eglinton Avenue East and Laird Avenue, has been the subject of numerous redevelopment proposals in recent years. Two of the larger proposals are the Kosmor site (Eglinton Ave/Brentcliffe Rd/Research Rd/Leslie St) and the Noble Cherry Development (Wicksteed Ave/Laird Dr/Commercial Rd/to east of Brentcliffe Rd).

As part the of development agreements for these sites, transportation related improvements have been identified and will be phased in as the developments proceed to full build out.

Recognizing the increased demand on the existing road network posed by planned and future redevelopment and the extent of traffic infiltration into the existing residential area west of Laird Avenue, opportunities to improve traffic flow between the Eglinton Avenue/Leslie Street area and Bayview Ave/Bloor St area need to be examined in greater detail. Given the foregoing, the Development Agreement between the former Borough of East York and Noble Cherry Development Limited required that a transportation study, including assessment of the Brentcliffe Road extension, be completed following final approval of this development.


The purpose of this study is to establish the need and feasibility from a transportation perspective for extending Redway Road to Bayview Avenue and Brentcliffe Drive from Wicksteed Avenue to Millwood Road, on the south side of the CPR Mid-Toronto subdivision. The need is to be determined based on the current and future traffic patterns in the study area and quantifies the impact on the extensions on the South Leaside community.

If the need and feasibility are established, this study could form the basis of the Environmental Assessment Study, which would be required for approval of these facilities.


The geographic limits for this study are Bayview Avenue, Eglinton Avenue East, Leslie Street and the Don Valley Parkway. The study area is shown on the attached map.

Key intersections within the study area are:

Eglinton Ave E/Brentcliffe RdLaird Dr/Millwood Rd

Eglinton Ave E/Laird DrBayview Ave/McRae

Eglinton Ave E/Bayview AveBayview Ave/Southvale Dr

Laird Dr/McRae Dr/Wicksteed AveLeslie St/Eglinton Ave E


4.1Work Program and Schedule

The proposal for consulting services that will be submitted in response to these terms of reference will be refined to reflect in detail the scope and work schedule of the study and will form the basis for the agreement between the City of Toronto and the Consultant.

4.2Data Collection

The Consultant will be responsible for the collection, organization, documentation and interpretation of appropriate data, including, but not limited to the following:

 i)Review of all relevant background materials and studies.

ii)Summarize the existing transportation operations in the study area:

-weekday AM peak period (7:00 am to 9:30 am), weekday PM peak period (4:00 p.m. to 6:30 p.m.) turning movement counts at all major intersections within the study area;

weekday AM and PM peak period origin-destination information for motorists using Bayview Avenue, Laird Drive/Millwood Road, South Leaside Streets (Southvale Drive, McRae Drive etc.) in sufficient detail to predict the potential volume and probable routes of traffic diverting from these roadways (interviews/questionnaire);

-weekday peak period travel time data on all arterial/collector routes in the study area;

-data on weekly peak period traffic that will be generated by new developments within or near the study area; and

intersection capacity analyses for key intersections identified in Section 3.0 above.

iii)Summarize the impact of approved and planned future development in the Leaside Industrial area taking into account transportation related improvements required as a condition of development approvals.

The City of Toronto will provide intersection turning movement counts no older than 2 years where available, however, these counts must be viewed in relation to potential changes in traffic patterns due either to new developments or recent road network modifications. The City will also provide all current traffic signal timings, parking and traffic regulations in the study area.

 4.3Data Analysis

The consultant will be responsible for determining:

Redway Road Extension:

The feasibility and necessity of extending Redway Road to Bayview Avenue, identifying constraints, and developing potential measures to promote the use of Redway Road as opposed to streets in South Leaside. The anticipated distribution of trips will need to be quantified as well as the amount of traffic that will divert from South Leaside to Redway Road. The impacts of the proposed extension on pedestrian and cyclists' movements should also be quantified.

The analysis should also indicate the effect that various traffic management initiatives introduced in South Leaside would have on traffic volumes on Redway Road. Historically, traffic management measures (turn restrictions, speed humps, chicanes etc..) proposed for collector streets in South Leaside have not received support from the community. Residents feared that motorists would find alternate streets in the area thus redirecting collector road volumes on these streets. The extension of Redway Road provides an alternate for motorists, which could allow for the introduction of traffic mitigation measures on collector streets in South Leaside.

Brentcliffe Road Extension:

identify opportunities for additional screenline crossings, including extending Brentcliffe Road southerly to the south side of the CPR Mid-Toronto rail line

re-assign traffic based on prevailing travel patterns and existing operational constraints

assess the benefits to the north/south corridors vs. the impacts in the new CPR rail line crossing environs

summarize the assessment of alternatives and identify preferred alternative(s)

 4.4Public Consultation

Public consultation will be required during this study. City Transportation staff will co-ordinate this public consultation. The Consultant shall provide City staff with technical support at all public meetings, this support is to include:

-preparation of display boards and drawings;

-preparation of overhead and/or slide presentations; and

-attendance by technical experts at all meetings to present technical issues and/or answer technical questions.

For the purposes of budgeting it is assumed that the following meetings will be part of the consultation program:

2 public information centres;

1 Works Committee meeting;

1 East York Community Council meeting;

1 Toronto Community Council meeting; and

1 City Council meeting (no presentation)

These meetings are in addition to meetings that will be required with City staff.


The final product of this study will consist of the following elements:

-10 copies of a report documenting the study process, findings and recommendations, including technical appendices which contain all of the background data collected and used in the analysis;

-functional plans for the extension of both Brentcliffe Drive and Redway Road, if deemed feasible, in both print and Intergraph Design File Format (DGN);

-preliminary cost estimates of the recommended road extensions.

 The final report may be included as part of a formal Environmental Assessment and therefore should be easily adaptable as a subsection of the EA report.


The study is to be initiated by October 4, 1999, and be completed in approximately 2.5 months, January 1, 2000, or as soon thereafter as considered reasonable following discussions with City staff.
