MONTREAL - Air Canada says it will begin flights between the Toronto Island airport and Montreal starting in February next year.

The airline says it expects to offer up to 15 daily flights from Billy Bishop Toronto City Airport to Montreal's Trudeau International Airport.

The new route will compete with upstart regional carrier Porter Airlines, which started flying out of the airport on Toronto's waterfront four years ago.

Air Canada has signed a letter of intent for five Bombardier Dash 8 Q400 turboprop aircraft that will be used on the route, which will be operated by Sky Regional Airlines Inc.

Air Canada was granted initial approval to fly into and out of the downtown Toronto airport in June.
