Air Canada will begin service to and from the Toronto Island airport  officially known as Billy Bishop Airport  on May 1, the airline announced Friday.The airline finally reached an agreement with the company that owns the only terminal at the airport.The effort to reach a deal was complicated by the fact that the terminal is owned by Porter Aviation Holdings, the owner of Porter Airlines  a direct competitor of Air Canada’s.

Until that agreement for use of the terminal was in place, the Toronto Port Authority, which runs the airport, could not finalize its operating agreement with Air Canada.Air Canada’s Toronto Island schedule will begin with up to 15 daily flights between Toronto and Montreal’s Pierre Trudeau International Airport.Air Canada will use Bombardier Dash 8 Q-400 turboprops  the same planes Porter Airlines uses. Jets are not allowed to use the airport. Air Canada’s island service will be operated by Sky Regional Airlines Inc.
