Launching March 31 next year, fares to Hamilton John C Munro airport, around 50 miles from Toronto, will start from €189 one way.
The low-cost Oslo-based carrier is taking bookings from Thursday (June 21).
Norwegian will operate the route using new Boeing 737 MAX aircraft with a single class 189-seat cabin.
Bjorn Kjos, Norwegian chief executive, said the route was a key milestone in the airline’s transatlantic expansion, its first service between Europe and Canada.
“We are committed to providing Irish passengers greater choice and lower fares across our network as we continue to invest in the Irish market,” said Kjos.
