Search by city (Montréal) to compare every airport serving the metro area in one query — low-cost carriers often use secondary airports with lower fares.

short-haul fares like this move fast in both directions — booking one to three weeks ahead is the usual sweet spot, and same-day walk-up fares are the worst case. These are booking windows, not rules — fares change constantly, so compare dates in the search above and book when the total, bags included, is right.

The cheapest month depends on the demand calendar at Toronto — school holidays, the Christmas–New Year peak and major local events price highest, and shoulder-season months between them price lowest. Rather than trusting a generic answer, open the fare calendar on the search above: it shows real prices for every date this month and next, so the cheap windows are visible immediately.

Midweek departures — Tuesday to Thursday — commonly price below Friday–Sunday on routes like Montréal → Toronto, because leisure demand concentrates at the weekend. The pattern is not guaranteed on every date, so compare a midweek date against your first-choice day in the search above before locking in.

It depends on your nationality, not on the route — two travellers on the same Montréal → Toronto flight can face completely different entry rules. Check the destination country’s official immigration site or your foreign-ministry travel advice for your passport, and do it before booking: some destinations require a visa obtained in advance, others issue visas or waivers on arrival.

Whatever the fare you buy includes — baggage is set by the carrier and fare class, not the route, and the carriers on this pair (Air Canada, Air Transat, WestJet) price bags very differently. Low-cost fares usually include cabin bags only and charge per checked bag; full-service fares typically include at least one. Compare totals with your bags added, because a dearer fare with bags included is often cheaper overall.

Toronto has a left-luggage network — the Union-to-airport UP Express turnaround is tight — a midday drop keeps the CN Tower hour FlyraGo’s Toronto luggage storage page lists the network, with flat daily rates you can book before you fly.
