Another founder member of the original ten-team Top Dog Football league, the Montreal Mayhem went much the same way as sister team Braveheart Chargers, managing just one losing season before being undone by the calling of fast cars and leaving the TDF family.

The Mayhem were replaced by the Severn Villains.
