WestJet Encore, the turboprop regional affiliate of Calgary-based low-cost carrier WestJet, will start eastern Canadian operations this week.

Encore launched last June and has focused on western Canadian flights during its first year of operation. On June 27, it will expand to the eastern part of the country by launching 4X-daily service between Thunder Bay, Ontario and Toronto. Encore operates an all-Bombardier Q400 fleet, connecting Canada’s smaller markets to WestJet mainline’s Boeing 737NG network.

Encore will operate 13 Q400s by the end of this month and plans to operate a fleet of 25 Q400s by the end of 2015.
