with the MMC model introduced in 2015. Canada BC Transit BC Transit, the first Canadian operator of double-decker transit buses, ordered nine Enviro500s, which were allocated to the Victoria Regional Transit System in Victoria, British Columbia with fleet numbers 9041–9049. These vehicles entered service in early 2005, joining the nineteen Trident 3 buses already in service since 2000. These were followed by another 26 (9501-9526) which entered service in 2008; sixteen of them (9501-9516) were originally allocated to Victoria and the other ten (9517-9526) to the Kelowna Regional Transit System in Kelowna. All units are currently allocated to Victoria. In 2009, BC Transit received one hybrid-electric Enviro500H (now numbered 9527) for evaluation, and followed it up in 2011 by purchasing one Enviro500 demonstration vehicle built in 2007 but repowered with an EPA 2010-compliant Cummins ISL engine (now numbered 9528). Three more Enviro500s (9529-9531) entered service in 2013, built in 2008 and acquired second-hand from OC Transpo (see below). All of these vehicles are used in Victoria. GO Transit GO Transit, the regional transportation authority serving the Greater Toronto Area in Ontario, currently operates 127 12.8-metre-long Enviro500s in its fleet. Like its fleet of coach buses, they have only one door in the front. Earlier, it tested a double-decker Trident 3 on loan from Victoria in May 2002, which had an extra rear door. However, it did not place any orders until early 2008, when it introduced twelve commuter-type Enviro500s (numbered 8000–8011), Ten extra units (8012-8021) entered service in early 2009. Both of these batches have a height of , making them too high to meet bridge clearance (under overpasses etc.) requirements in the province. After the introduction of the Go-Anywhere version of the Enviro500, In 2012, GO Transit ordered 25 of these new models (8101-8125), also long. The first bus was delivered on 3 April 2013 and the remaining 24 in May 2013. These were followed by seventy in 2014, delivered in two batches (8126-8165 and 8166–8195), and a further ten (8196-8205) in 2015. OC Transpo OC Transpo of Ottawa, Ontario, purchased three transit-type Enviro500s in 2008 as part of a one-year pilot project to investigate the use of double-deckers on high-capacity routes. Numbered from 1201 to 1203, they were operated on a variety of routes, but their height, which exceeded the requirements of the MTO, made them impractical for continued use. These three demo buses were sold to BC
