Despite the lower height, these buses are still too high to fit in a number of GO terminals, namely Hamilton, Yorkdale, York Mills, and Union Station. Beginning in 2016, GO Transit began placing further orders of Enviro500 double-deckers. These buses, designed specifically for the GO Transit network and designated as "Super-Lo", have an even lower height of , low enough to operate on virtually the entire GO bus network. They also have a longer length than previous orders, being long (the same as its coach buses), and dedicated space for luggage at the rear. The chassis for these vehicles are being locally assembled at a newly established facility in Vaughan, creating up to 30 new full-time jobs.
