From November 1, outbound service AC050 will depart Toronto at 2055 on Mondays, Wednesdays, Fridays and Sundays and land in Delhi at 2115 the following day.
Return service AC051 will leave Delhi at 0045 on Tuesdays, Wednesdays, Thursdays and Sundays and arrive in Toronto at 0500 the same day.
All flights will be operated by the B787-9, apart from the Monday outbound service and the Wednesday return service, which will be B787-8 aircraft.
Calin Rovinescu, Air Canada's president and CEO, said: "We will be offering the only non-stop flight from Canada to India using our newest Boeing 787 Dreamliners, which are revolutionising long-haul air travel.
"The operating economics of these new aircraft make this service feasible and it will be the first route dedicated to the larger, 787-9 version of this aircraft, which begin entering our fleet in 2015."
In September, Air Canada announced a series of new codeshare routes with Star Alliance partner Air India
