In 2012, GO ordered new Enviro500 double-decker units for its fleet. Designated as "Go-Anywhere" models, they have a redesigned front end, based on the Enviro400 (and which would later form the basis for the global Enviro500 MMC refreshed design), and a height of , lower than the previous models. The lower height allows these buses to meet many more clearance standards as a result and are used on a wider variety of routes, including those that travel on Highway 401. Three additional batches of "Go-Anywhere" Enviro500s were ordered until 2015.
