Aviation analytics firm Cirium said that as of Monday afternoon, August 18, Air Canada had called off at least 1,219 domestic flights and 1,339 international flights since last Thursday, when the carrier began gradually suspending its operations ahead of the strike and lockout.

Flight attendants went on strike after Air Canada gave wage increases to certain employees, including pilots with a 26% rise in 2024, a mostly male-filed role according to CUPE. In contrast, the union said that flight attendants, who are mainly women, received a lower 8% increase in 2025.
