These requirements apply in addition to and separate from any other municipal by-law or legislative requirements, including but not limited to those under the Toronto Municipal Code Chapters 681 and 851 or the Ontario Building Code.

Residential, Residential Mixed-Use, or Commercial Office Point Tower Developments

Every point tower shall have its own independent service connection to the municipal potable water and sewer services, including all associated stormwater management facilities. For clarification, this applies regardless of any shared podium structures, common underground parking structures, or anticipated ownership structures (including all forms of condominium ownership). Any podium that provides a base for more than one point tower shall also have its own independent service connection to the municipal potable water, storm, and sanitary sewer services.

Residential or Residential Mixed-Use Townhouse Developments

Every anticipated standard or common-elements condominium corporation shall have an independent servicing connection to the municipal potable water and sewer services, including all associated stormwater management facilities.

Unless otherwise notified in writing at the time of application, staff will review all townhouse applications on the assumption that they will form part of one standard or one common-elements Condominium Corporation. If any party, including but not limited to the applicant and all subsequent owners of the development, applies for more than one condominium corporation encompassing any or all of the development, different service connections, including revised plans and studies, may be required by the City at the sole cost to the condominium applicant.

All Other Commercial and Industrial Development

Every parcel of land that will be separately conveyable requires its own servicing connection to the municipal potable water and sewer services, including all associated stormwater management facilities. In this situation, each condominium corporation will be considered one parcel of land.

Unless otherwise notified in writing at the time of application, staff will review all commercial and industrial applications on the assumption that they will form part of one parcel of land.

                    Attachment 1 – Servicing Requirements for Different Built Forms

                    The following potable water, storm and sanitary sewer servicing requirements apply to all new development applications in the City of Toronto, excluding residential developments of less than 5 dwelling units. These requirements apply in addition to and separate from any other municipal by-law or legislative requirements, including but not limited to those under the Toronto Municipal Code Chapters 681 and 851 or the Ontario Building Code.

                    Residential, Residential Mixed-Use, or Commercial Office Point Tower Developments

                    Every point tower shall have its own independent service connection to the municipal potable water and sewer services, including all associated stormwater management facilities. For clarification, this applies regardless of any shared podium structures, common underground parking structures, or anticipated ownership structures (including all forms of condominium ownership). Any podium that provides a base for more than one point tower shall also have its own independent service connection to the municipal potable water, storm and sanitary sewer services.

                    Residential or Residential Mixed-Use Townhouse Developments

                    Every anticipated standard or common-elements condominium corporation shall have an independent servicing connection to the municipal potable water and sewer services, including all associated stormwater management facilities.

                    Unless otherwise notified in writing at the time of application, staff will review all townhouse applications on the assumption that they will form part of one standard or one common-elements Condominium Corporation. If any party, including but not limited to the applicant and all subsequent owners of the development, applies for more than one condominium corporation encompassing any or all of the development, different service connections, including revised plans and studies, may be required by the City at the sole cost to the condominium applicant.

                    All Other Commercial and Industrial Development

                    Every parcel of land that will be separately conveyable requires its own servicing connection to the municipal potable water and sewer services, including all associated stormwater management facilities. In this situation, each condominium corporation will be considered one parcel of land.

                    Unless otherwise notified in writing at the time of application, staff will review all commercial and industrial applications on the assumption that they will form part of one parcel of land. If any party, including but not limited to the applicant and all subsequent owners of the development, applies to sever or condominiumize any part of the development, different service connections, including revised plans and studies, may be required by the City at the sole cost to that applicant.

                    Other Forms of Development, Including Phased Development and Phased Condominiums Under Part Xl of the Condominium Act

                    Every building shall have its own independent servicing connection to the municipal water and sewer services, including all associated stormwater management facilities, regardless of any shared podium structures, common underground parking structures, or anticipated ownership structure (including all forms of condominium ownership).
