Domestic and internal flights in Canada

Canada spans six time zones, so flying is often the only practical way to move between its main regions. Airlines flying within Canada include Air Canada, WestJet, Porter Airlines and Flair Airlines, with frequent services across the transcontinental corridor and feeder routes into smaller regional airports. Most travellers fly domestic to cover continental distances in hours rather than days or to reach the Atlantic provinces and the far north. If you’re flexible, our travel hacks show how small changes, mid-week dates, alternative airports, off-peak hours, often reveal noticeably cheaper domestic fares.

The cheapest domestic flights in Canada usually come from flying mid-week where possible, avoiding peak holiday periods, and being open to alternative airports, flying into Toronto or Vancouver can drop the fare on similar journeys.
