I don't see us getting kicked out out G7 (economic) or NATO - but whether we have any pull is another question (what are you going to do, act like Turkey when no one listens to us, or France?). The real issue is we were shut out of AUKUS - the apex of the military alliance.
I think we'll see more setups like AUKUS where Canada is just bypassed when new arrangements are made. Eventually, some of these current forums will be deprecated. But I guess we can still pretend to be important till that happens.
