Air Canada Rouge will add four weekly non-stop flights onto its Dublin to Toronto route this summer.
The second service will be operated by a B767-300ER aircraft in a two-cabin configuration with 280 seats - 24 in Premium Rouge and 256 in Rouge, including 35 Rouge Plus seats with additional legroom.
Between June 13 and September 16, outbound service AC1928 will depart Toronto at 1855 and arrive in Dublin at 0625 the next day, with return service AC1929 leaving Dublin at 0900 and landing in Toronto at 1120.
It will run alongside the airline's year-round AC1908/AC1909 service between the two cities, which will turn daily on June 28.
Flight AC1908 takes off from Toronto at 2310 and lands in Dublin at 1040 the next day, and AC1909 departs Dublin at 1225 and arrives in Toronto at 1445.
Robert Atkinson, Air Canada's general manager UK, Ireland and Northern Europe, said: "We are pleased to offer our customers travelling from Dublin even greater access to Toronto and beyond with increased flight frequency this summer.
"These additional flights complement our existing service for Irish customers, offering convenient connections to destinations across North, Central and South America as well as the Caribbean through our Toronto hub."
Last week, during an interview with Business Traveller, Air Canada defended its decision to install tightly-configured seating in economy on its B787-9 Dreamliner and B777-300ER aircraft (see news, February 6).
