The Shannon market is becoming saturated, and there is not room for 8 transatlantic destinations from 6 airlines. Give it a couple of years and some of these routes will be scrapped.
Regarding Bombardier, I know people who work for the company and there are a few employees who regularly fly to Montreal. However a) most if not all of them fly in economy class and not business; b) we're talking fewer than 100 round trips a year; and c) if BFS was to get a Canadian route it would be Toronto and not Montreal, meaning it would not be that much handier for Bombardier employees than flying via LHR or AMS.
It is worth noting however that a couple of years ago Willie Walsh was interviewed about BA's Belfast route, and he said that Toronto (as well as Hong Kong, and Copenhagen) were the most popular destinations for NI connecting passengers. That would suggest that there is potentially some extra demand for a Toronto route.
