TTC Green Initiatives
While the TTC continues to modernize our service, introducing additional green initiatives are essential in the process. These green features are some of the ways the TTC is leading the charge on the transition to a greener future for transit.

The eBuses operate on truly green technology with the potential for zero emission. Zero emission buses have no tailpipe emissions, and in Ontario, generation of electricity for overnight charging is 100% nuclear and completely free of GHG emissions. The TTC now has one of the largest mini-fleets of electric buses in North America and this green initiative is part of the TTC’s commitment to be 50% zero emissions by 2028-2032 and 100% zero emissions by 2040.
While the eBuses should be capable of 200km or more on one charge, they are currently being deployed on routes that are 75km or less. With time and confidence, they will be deployed on longer and longer routes. The TTC has purchased 60 all-electric buses from three manufacturers: 25 from Proterra Inc., 25 from New Flyer Industries Inc. and 10 from BYD Canada Co. Ltd. On Monday, June 3, 2019 the first New Flyer eBus went into service on the 35 Jane route. On Saturday, October 26, 2019 the first Proterra eBus went into service the 6 Bay route. On Tuesday, September 8, 2020 the BYD Canada Co. LTD. eBus went into service the 116 Morningside route.
Fun fact! During long-term hydro power outages, or in the event of an emergency, there is potential for these buses to serve as mobile power plants. A bus with a 440,000-watt battery on board can be plugged into a building, such as an emergency response center or hospital, to provide electricity.
TTC partnership with OPG and Toronto Hydro
The TTC is very excited to be working with Ontario Power Generation (OPG) and Toronto Hydro-Electric Services Limited on leading-edge green infrastructure to support the further electrification of our fleet. This partnership, between a public agency, municipally-owned company and corporation, to deliver full fleet electrification and a greener future, is a first for all three parties. The program delivery model, in which a transit agency works with its hydro utilities to invest in, deliver, own, and operate public transit electrification infrastructure, is also an area of significant innovation where TTC is taking a lead role in advancing industry best practices. One of the benefits of working with OPG and Toronto Hydro on this project is that they understand the infrastructure, they have an inherent interest in the success of fleet electrification, and just as with TTC, they have a greater duty to serve the public and deliver safe and reliable service.
We look forward to advancing commercial negotiations and finalizing agreements to move ahead with designing and later building, operating and maintaining all electrification infrastructure required to implement the TTC's Green Fleet Program. The electrification of TTC's buses demonstrates a strength of commitment made by the City of Toronto, Province of Ontario, and the Government of Canada. The TTC's eBuses are critical to reducing global greenhouse gas emissions and improving local air quality for the people of Toronto.
The hybrid buses incorporate series technology and run off power generated on-board. As opposed to an electric bus that is plugged in to charge, our hybrid buses use on-board generators that are powered by diesel engines. Though these vehicles are still using fuel to produce energy, they use a lot less than the average vehicle. Hybrid buses also incorporate the recovery of braking energy, meaning that energy produced when descending a hill or during braking is fed back to the energy storage system to reuse for propulsion, resulting in approximately 25% fuel reduction and in turn, reduced tailpipe emissions. The TTC plans to have 55 hybrid buses delivered by the end of 2018 and 200 more hybrid buses delivered by the end of 2019.
Fun fact! One bus at full capacity takes the place of 70 single occupancy cars. The clean-diesel bus produces less than 1/10 the emissions per passenger than a personal vehicle.
TTC Green building features
- The McNicoll Bus Garage has the largest green roof in Toronto, roof-top solar panels and a storm water retention system with a reservoir having a capacity of an Olympic-sized pool.
- Downsview Park Station features sweeping lush vegetated green roofs at both the east and west entrance buildings.
- Finch West Station’s design includes a cool roof over the main entrance and a green roof over the elevated substation box.
- York University and Highway 407 Stations feature metal cool roofs that have a high solar reflectance and absorb little heat.
- Pioneer Village Station includes cool roofs over the entrance buildings and green roofs over the TTC bus terminal and substation.
- Vaughan Metropolitan Centre station features a cool roof on the main entrance and a green roof on the south side of Highway 7 on the electrical substation.
- Leslie Barns’ one-of-a-kind rooftop is low maintenance and can sustain sedums, grasses and other low herbaceous vegetation, while also providing a habitat for insects and birds. The large storm management pond collects water from the drainage system in the parking lot and is then used to water all of the plants on the green roof.
- The TTC’s first green roof is located at Eglinton West Station with an 835-square-metre garden.
- Victoria Park Station was one of the first TTC stations to participate in the green roof pilot project. The design enhances the beauty of the station, while also diverting 300,000 gallons of storm water from the sewer system annually.
