I agree on the part of the Rizzutos not being completely decimated, I meant to say the hierarchy, which apart from from Rizzuto Jr were completely wiped out.

Montagna was a rising star in the Bonanno family and he clearly had a fair amount of influence in Canada following his deportation, very risky move trying to oppose Rizzuto, but he was nearly successful. If Rizzuto wasn't in the can at the time he'd almost certainly have been killed.

The Bonannos have had no influence in Canada since Joe Massino flipped, nor any other American LCN family, they're too busy trying to rebuild there own families, nobody has the time or man power to set up crews in Canada.

As for your comment on all the US guys flipping, the only reason the Canadians don't is due to the fucked up justice system.

The Gambinos, Genovese, Lucchesse and Bonnano's are all still bigger crime families then Rizzuto family, none of the NY families are decimated, all be it the Colombo's are fucked. Genovese are far far stronger, as are the Gambinos.
