Hells Angels are pretty much the only organized crime in Winnipeg these days. I heard the Winnipeg chapter is on probation because of it (that's just what I heard, no idea if it's true). They got hit hard in the early 00's and pretty well the only guys on the streets are members of their puppet gangs (zigzag crew and redlined support crew) if I understand correctly.

the Rock Machine tried to move in a year or two ago but it doesn't seem like that has gone well for them. The puppet gangs are dead set against them moving in and the RM doesn't seem to have the support of any of the street gangs (of which there are dozens).

In Canada though, the HA are pretty much the only viable OMC. Someone correct me if I'm wrong, but that's the impression that I get.
