There are a few different anglophone accents in Montreal.
This Gazette link compares the accents of Montrealers of Jewish, Italian and British Isles origins. These are pretty good examples of the different accents actually.

The differences are largely due to different anglophone communities being a bit segregated from each other without one anglo group dominating throughout the whole city.
