511 Züm Steeles

511 Zum Steeles is a bus rapid transit route in Brampton, Ontario, Canada, serving Steeles Avenue. The final corridor outlined in Phase 1 started service on November 26, 2012.

The main route runs from Lisgar GO station in northwest Mississauga east to the Humber College Bus Terminal, the western terminus of the Line 6 Finch West light rail route at Humber Polytechnic Humber North Campus, which is located at Highway 27 and Finch Avenue in Toronto. It makes connections with various local and express bus services at Brampton Gateway Terminal and Bramalea GO Station. Though largely industrial through Brampton, Steeles Avenue sees bus service every six minutes on current route 11. In September 2015, limited service on 511 Zum Steeles was extended to Lisgar GO Station operating only on weekdays. Eventually, full service on the entire route were implemented.

The route was suspended past Chinguacousy Road in March 2021, after nine drivers tested positive for COVID-19. It was noted that the route led to a "large logistics business," in the midst of an outbreak. Shortly after, the outbreak was confirmed to be Amazon. Peel Public Health Medical Officer of Health Dr. Lawrence Loh denied there was a connection between the two outbreaks.

On December 22, 2022, 511 Zum Steeles along with its local route 11/11A Steeles entered the newly built bus terminal at Bramalea GO Station. This marks the first time that these routes directly serviced the station, as previously they stopped on-street at the intersection of Steeles Avenue and Bramalea Road.
