Union leaders for Air Canada’s flight attendants said members would return to work after a deal was reached to end a three-day strike that grounded hundreds of flights, hitting around 500,000 customers.

Air Canada’s unionized flight attendants reached an agreement with the country’s largest carrier, the union said on Tuesday.

More than 27,000 signatories are demanding for the removal of Jobs Minister Patty Hadju over her handling of the Air Canada labour dispute.
