I don't think Air Canada's activities need to be restricted since it is the main carrier in Canada. It is our flagship carrier in a sense. Traditionally, Air Canada has always been dominant and it now accounts for roughly 50% of the market.
It is true that Air Canada accounts for a lot of activity at the Montréal-Trudeau international airport, but that has not always been the case. In the past, Air Transat had more international destinations than Air Canada did. So there is already competition in international flights. I don't think that is the concern.
