WestJet Airlines is restoring operations after reaching a tentative agreement with unionized mechanics to end a strike that began on Friday.

The airline, Canada’s second largest, expects further disruptions in the coming week as it gets aircraft and crew back into position, according to a company statement. The strike led the carrier to cancel more than 800 flights and park 130 aircraft at 13 airports across the country during the Canada Day holiday weekend, one of the busiest travel times of the year.
