Air Canada (AC, Montréal Trudeau) has finalized an agreement with Bombardier Aerospace (BBA, Montréal Trudeau) for the order of forty-five A220-300s with options for thirty more. Deliveries are scheduled to begin in late 2019 and extend through to 2022.

The purchase was first announced as a Letter of Intent (LOI) in February and follows the Canadian parliament's recent decision to amend the Air Canada Public Participation Act (ACPPA) which governs where the carrier is mandated to carry out aircraft maintenance domestically.
