While being just above the border means much of the fire apparatus do not differ from their American counterparts, we focus instead on some variants we’ve noticed:

The Thibault/Mack configuration is popular in Québec, particularly in Montreal.

Toronto also employs the Mack, as shown here.

Montreal unit 27-3 (Côte-des-Neiges, I believe, Region 9, Outremont), which is a Freightliner aerial. It looks suspiciously similar to the same 27-3 (with a different unit name, 720 instead of 716) that has been identified as a 1989 Freightliner with a Bronto Skylift Elevating Platform.
