1.0 Introduction and Background
1.1 Introduction
Toronto City Council recently confirmed support for an extension of the Bloor-Danforth Subway from
Kennedy Station to Scarborough Centre and Sheppard Avenue. This subway extension will replace the
aging Scarborough Rapid Transit (SRT) line. The City of Toronto with support from the Toronto Transit
Commission (TTC) is undertaking the Scarborough Subway Extension Project Assessment (SSEPA) to
determine key aspects of this rapid transit project such as route alignment, station locations, construction
methods, maximizing benefits to local communities and strategies for mitigating adverse impacts. A
recommended alignment and station locations will be presented to the TTC Board and CityCouncil for
approval at the conclusion of this study.
A Transit Project Assessment Process (TPAP) is required before the City and TTC may proceed with
implementation and construction. The TPAP is a streamlined self-assessment process for transit projects
to satisfy the requirements of the Environmental Assessment Act; which is administered by the Ministry of
the Environment and Climate Change. The TPAP is a final project review which will assess potential
environmental impacts and identify proposed mitigation strategies to be employed during the design,
construction and operation of the project.
1.2 Project Background
The SRT line opened for service in 1985 and it operates between Kennedy Station on the Bloor-
Danforth Subway and McCowan Station. After almost 30 years of continuous operation, the SRT’s
vehicles are reaching the end of their normal lifespan. The SRT would need significant rehabilitation,
new vehicles, and updated technology in order to support existing and future transit service needs and
address the problems associated with the aging SRT Line.
There has been considerable study and discussion in recent years about the preferred manner in which to
address the problems on the aging SRT line. In 2006, the TTC evaluated options to upgrade or
replace the SRT; completing the SRT Strategic Plan – a comprehensive study of options for replacing
the aging vehicles, upgrading the system’s infrastructure as necessary, and potentially expanding the
line. The initial recommendation was to purchase larger, new generation SRT vehicles, and make the
physical modifications at SRT stations that were necessary to accommodate the new, longer vehicles.
In 2007, one year after the SRT Strategic Plan – the Transit City Light Rail Plan was introduced, which
called for the implementation of seven light rail lines throughout the City of Toronto. In that context, it was
recommended that the SRT rehabilitation adopt light-rail technology in order to take advantage of the
economies-of-scale cost savings which would result from the acquisition of a large fleet of light-rail
vehicles to operate on the proposed City-wide network.
An Environmental Assessment (EA) for the replacement of the SRT with light rail vehicles, including a
complete rehabilitation / reconstruction of the existing elevated structure, was completed in 2010. The
proposal was to extend the new line beyond its current terminus – at McCowan Station – to Centennial
College and then north to Sheppard Avenue. The EA also addressed a second, future extension north of
Sheppard Avenue, to the Malvern Town Centre.
Most recently, in 2013, the TTC Board, and subsequently, City Council, confirmed support for replacing
the SRT with an extension of the Bloor-Danforth Subway, with stations at Lawrence Avenue,
2

Scarborough Centre and Sheppard Avenue – where the subway would interconnect with the future
Sheppard East LRT line. Council’s decision to extend the Bloor-Danforth subway north and east into
Scarborough is based on the following benefits:
• Higher speed;
• Most-reliable, highest-quality rapid transit service;
• Elimination of the transfer at Kennedy Station;
• Higher ridership; and
• Consideration of alignments other than the existing SRT routing, which would then not
require shutting down the SRT during construction of a subway extension.
All decisions relating to the alignment and station locations are subject to a further EA.
The SRT service has been very successful in attracting ridership and has been operating over-
capacity for a decade. For many years its peak-period passenger volumes have been maxed-out at 4,000
passengers per hour, with no ability to improve the capacity because of the limited number of vehicles in
the fleet and limited station size. Analysis to date has shown if the SRT were replaced by a continuation
and extension of the Bloor-Danforth Subway north to Sheppard Avenue, it would carry passenger
volumes of upwards of 9,500 passengers per hour per direction (pphpd) in the busiest hour of travel. The
additional ridership results from the higher operating speeds between the key points of Sheppard Avenue,
the Scarborough Centre and Kennedy Road. The elimination of the existing SRT/subway transfer at
Kennedy Station also contributes to increased passenger convenience which in turns increases trip
attractiveness and ridership.
1.3 Planning Context
The planning framework for the Study Area is established under the Province’s Growth Plan for the
Greater Golden Horseshoe, The Big Move regional transportation plan by Metrolinx and the Toronto
Official Plan. Key growth areas within the Study Area include Scarborough Centre, sections of Lawrence
Avenue and Sheppard Avenue, and existing and planned transit stations.
• Locally and provincially, Scarborough Centre is identified as a major focal point for growth. It
is a locally-designated Centre under the Toronto Official Plan, and a provincially-
designated urban growth centre under the Growth Plan. Scarborough Centre is targeted to
achieve a minimum density of 400 residents and jobs per hectare by 2031, and is subject
to a Secondary Plan and complementary precinct-level plans that provide direction for
future development.
• Major transit station areas are also identified under the Growth Plan for the Greater Golden
Horseshoe as important nodes where transit supportive development will be encouraged.
The most important station areas are identified as Mobility Hubs under The Big Move.
Within the study area, the area around Kennedy Station is identified as a Gateway Mobility
Hub and Scarborough Centre as an Anchor Mobility Hub.
• Under the Toronto Official Plan, the designated Avenues in the Study Area are also
intended to accommodate significant growth. These areas include sections of
Lawrence Avenue and Sheppard Avenue East.

1.4 Transit Planning in Toronto
A comprehensive, high quality, affordable transit system that lets people move quickly and conveniently
throughout the City is key to high quality of life as envisioned in the Toronto Official Plan.
The Scarborough Subway Extension is being planned in the context of the overall transit network. As part
of the “Feeling Congested?” Official Plan Review Process, 25 Rapid Transit Projects are being reviewed
and prioritized. The principles of "Feeling Congested?" guide the City's work on the full range of transit
projects.
Related Projects
Three important projects – the Scarborough Subway Extension, SmartTrack and Relief Line - are very
closely related and are currently being studied in a coordinated fashion by City Planning in partnership
with the TTC. Work on the Scarborough Subway Extension will inform the other projects and work on
SmartTrack and Relief Line will inform work on the Scarborough Subway Extension. Aligned
recommendations will be presented to the TTC Board and Toronto City Council.
Regional Express Rail (RER) is an enhanced service concept providing at least 15-minute all-day
service on all existing GO Rail corridors. RER is currently being developed by Metrolinx and the
Province. SmartTrack builds on RER, comprising 3 of the 7 existing GO Rail corridors. The impact of
RER and SmartTrack on how the Scarborough Subway Extension meets its objectives will be a key
consideration and will be carefully and thoroughly studied as part of the Project Assessment.

• Project objectives;
• Study process including approach to consultation;
• Existing conditions and assumptions;
• Long list of reasonable alternatives; and
• Evaluation criteria.
Following consultation on Phase 1, this document has been finalized and guides the subsequent study
phases.
Phase 2 – Choosing the Corridor
• Finalize evaluation criteria;
• Apply the evaluation criteria to reasonable options to develop a short list of possible
corridors
• Within the short list of possible corridors:
− Develop alternative station location options
− Develop a list of possible alignments
• Apply the evaluation criteria to the short list of possible corridors to select a preferred
corridor
• Application of the evaluation criteria to short list corridors; and
• Station location options and alternative alignments within the short list of possible corridors.
Phase 3 – Recommending the Alignment and Station Locations
• Apply evaluation criteria to select preferred station locations and alignment;
• Create a functional design for the recommended alternative; and
• Identify potential impacts and appropriate mitigation strategies associated with the
recommended design.
• Recommended station locations and alignment;
• Functional design of stations; and
• Potential impacts and proposed mitigation strategies.
At the end of Phase 3, a draft Environmental Project Report identifying the recommended station locations
and route will be prepared. Authority will be sought to commence the TPAP for final project review from
the TTC Board and Toronto City Council at the end of Phase 3.
Figure 2-2 below illustrates the phased approach being used to determine the alignment and station
locations for the Scarborough Subway Extension.

Phase 4 – Final Project Review - Transit Project Assessment Process
Phase 4 of the project assessment will satisfy the requirements of the Environmental Assessment Act and
TPAP:
• Summarize and review the analysis and decision-making of the project assessment;
• Finalize the Environmental Project Report; and,
• Seek authority to proceed with construction of the Scarborough Subway Extension from
Toronto City Council and the Province of Ontario.
It is anticipated that the TPAP will be undertaken in early 2016. The process will provide opportunity for
the public to review the work of the project assessment and provide any additional input. Based on
this further input, the Environmental Project Report will be finalized and a Statement of Completion will be
published and submitted to the Minister of Environment and Climate Change. After a review period of
9

approximately three months, the City will be able to proceed with implementation of the subway extension
as per direction of the Minister.
More information about Ontario's TPAP can be found by accessing the following links:
• Ontario Regulation 231/08
• Guide to Environmental Assessment Requirements for Transit Projects
2.5 Appropriate Timelines
The SSEPA will be expedited in all reasonable ways while including appropriate opportunities for
community involvement and public input. We anticipate that the planning and preliminary engineering
work (Phases 1-3) will be complete by late 2015/early 2016, but recognize that this work is partially
dependent on findings of studies related to SmartTrack and the Relief Line as per Section 1.4. Aligned
recommendations to the TTC Board and City Council are critical for effective transit planning and will
require careful coordination of all three projects.
Decisions made through the project assessment will lead to a Transit Project Assessment Process
(TPAP); a focussed and streamlined approvals process that satisfies the requirements of the
Environmental Assessment Act. The project schedule has been set up to complete the necessary work to
meet TPAP requirements. The TPAP itself will take no more than six months, and is anticipated to be
complete be the mid-2016.
The City and the TTC will seek to expedite detailed design and construction processes once authority to
construct has been received. Construction is anticipated to commence in 2018 and the subway is
expected to be in operation in 2023.
2.6 Evaluation Approach and Criteria
The development of the Evaluation Criteria is based on the City’s list of 8 decision-making criteria that
have been identified through the Official Plan review of transportation policies to guide Toronto’s
decisions on transportation investments. The intent of adopting these factors for the evaluation of the
Scarborough Subway Extension's alignment and station location options is to have an aligned vision and
to employ similar criteria in making investment decisions about transportation projects.
The evaluation of alternatives will be comprehensive (relative to the City's 8 decision-making criteria,
study objectives and Study Area), understandable, replicable, traceable and participatory (involving input
from interested and potentially affected stakeholders). The process of selecting the recommended
alignment will be based on the identification of the alternative that best serves the City's list of 8 decision-
making criteria, project objectives and sub-objectives. In order to focus the analysis, specific measurable
criteria have been created to correspond to each objective.

3.0 Public Consultation
3.1 Public Consultation Guiding Principles
The goal of the project’s proposed public consultation program is to generate broad participation and
solicit input from community leaders, stakeholders and the public. Participation by those with local, city-
wide and regional interests will strengthen the project and lead to the successful implementation of the
subway extension.
The public consultation will be guided by the following principles:
Inclusiveness.......engage the widest possible audience through multiple
consultation opportunities;
Timeliness............offer early and ongoing opportunities for participation well before
decisions are made;
Transparency.......participation will be widely communicated through multiple
communications channels;
Balance ................provide opportunities for a diversity of perspectives and opinions to
be raised and considered;
Flexibility..............adapt as required to meet the needs of participants; and
Traceability ..........demonstrate the impact of participant input on decision making.
3.2 Public Consultation Plan
A draft Public Consultation Plan will be developed to outline the engagement methods and approach that
will be used in all phases of the SSEPA. The plan will be finalized after receiving input from the public
during Phase 1.
The City will design a community engagement program that will work collaboratively with the
community, local businesses, agencies and other affected stakeholders to seek input throughout the
project assessment and the TPAP. While the proposed public consultation process follows a structured
approach, it will also allow for flexibility in engaging stakeholders and encouraging dialogue with the
public around key issues related to the project.
In each phase of the project, engagement will consist of four main communication approaches:
• information sharing;
• online consultation;
• live events; and
• community outreach.
1. Information Sharing
The City will share information about the project throughout the study process. Regular updates
will be shared through the project email list, City social media accounts and print material such as
project briefs. The project website will be regularly updated and will act as the hub for information
11

2
about the project. Key documents produced will also be made available through the project website.
The Study Team will look to translate key documents when appropriate throughout the study.
2. Online Consultation
The City will solicit comments and feedback on key decisions during each phase of the project
through the website. Online consultation will be one of the primary foci of consultation because it has
the ability to engage a large number of people from many different areas in a short period of time.
3. Live Events
Open houses, public meetings, Stakeholder Advisory Group meetings and workshops will be held
at various key points in the study for interested stakeholders and residents throughout the City to
learn and provide their input into key decisions of the project.
4. Community Outreach
The City will host community group meetings to proactively educate and solicit feedback from
the community. Community outreach will focus on the local areas where the Scarborough Subway
Extension will be located.
