The document provides an update on construction of the Crosstown LRT project in Toronto, specifically focusing on the West At-Grade section from Brentcliffe to Victoria Park and the Science Centre Station. It summarizes that preparatory works are underway at both locations, including geotechnical investigations, utility relocations and tree protection. At Brentcliffe, piling for support of excavation is nearly complete. At Science Centre Station, piling is underway and existing traffic staging has been installed to support upcoming works like piling, utility relocation and road widening. Renderings of stations along the West At-Grade section and of the Science Centre Station are also included.

Agenda
• West At-Grade (East Portal to Victoria Park Stop)
Update
• Science Centre Station Update

3. 3
What Are We Building
• 15 underground stations and 10 surface stops – 9 km below ground and 10 km
above ground
• A maintenance and storage facility
• A 19-kilometre route separated from regular traffic
• Transit communications system
• Links to 54 bus routes, three subway stations, GO Transit, and a new UP Express
station

4. 4
Safety First – Our #1 Priority
We train and direct staff to:
• Always have a site specific safety plan and site specific emergency plan.
• Ensure pre-work hazard assessments are complete and understood.
• Ensure job hazards analyses are complete and understood.
• Do everything possible to protect themselves, co-workers, and members of the
public.
• Stop work if the safety of themselves, co-workers and members of the public cannot
be assured.
• Identify and report unsafe behaviour and coach each other to make improvements.
• Be prepared and equipped to work safely.

Crosstown Design Approach
Street Level – Contextual and
Inviting
An International Signature for
Toronto
Entrance – Bright & Secure
Concourse – Simple & Pristine Concourse – Transparent & Open Platform – Spacious & Animated

6. 6
Accessibility
Station and Stops are designed to be universally accessible, including satisfaction of the
AODA, applicable City of Toronto Guidelines, the OBC, and CSA Standards.
Some of those features include:
• Barrier‐free paths from the entrance level to the station
platform level
• Tactile warning strips and tactile walking surface
indicators
• Signage systems with tactile indicators
• Passenger Assistance Intercoms (PAI)
• Low floor Light Rail Vehicles (LRV) with designated
wheelchair locations
• Nominal gaps from platform edges to LRV entries
• Automated visual and audible stop announcements
• On-street and off-street paratransit passenger pick-ups
and drop-offs

7. 7
Environment & Sustainability
During Construction
• Programs to minimize impact on wildlife, their habitats, watercourses and trees
• Reduce impact on our community neighbours through the management of dust,
noise and vibration
• Sustainable construction practices, including active management of construction
and demolition generated wastes, targeting 75% waste diversion from landfills;
and off-site beneficial reuse of excess soil.
Project Design Sustainability
• Project wide application of Toronto
Green Standard
• LEED Certification at EMSF
• Bike parking for short- and long-term
users
• Dedicated pedestrian routes
• High Solar Reflectance Index paving
• Green roofs
• Water use conservation/efficiency
• Fritted glazing (minimize bird
collisions)
• Shielded exterior lighting (prevent off-
site light trespass)
• Sheltered waiting areas
• Energy efficiency – LED lighting, heat
recovery systems
• Landscaping – use of native, drought-
tolerant plants and large trees
