A CAD calendar for Quebec travellers
This page maps relative pressure on Montreal to Toronto flights — which months usually feel expensive for travellers departing YUL, which ones often soften, and how the Friday tax dominates this short domestic sector. It is not a promise of a specific dollar amount. Live CAD inventory via Travelpayouts is the source of truth.
Quebec calendars matter: March Break (vacances scolaires), construction holiday (vacances de la construction) in late July, and Christmas–New Year all firm demand. Construction-holiday weeks can feel more like a second March Break on leisure seats — plan accordingly.
Pair with March Break flights from Montreal when school dates lock, and compare peer short-hauls like Montreal to New York when a US weekend is also on the table.

03 · Midweek vs weekend
The Friday tax on an 80-minute hop
On YUL–YYZ, day-of-week usually matters more than month. The expensive pattern is familiar: Friday afternoon westbound and Sunday evening eastbound. Business travellers and weekend leisure stack those banks. If your calendar allows a Tuesday outbound and Thursday return, run both searches in CAD before you commit.
Train and car alternatives exist, but when you do fly, first-wave mornings and standard daytime midweek nonstops usually beat red-eyes for sane downtown arrivals. REM / 747 bus tips for YUL live in the airport guide.

How Quebec travellers usually win on this route
Protect midweek first — then worry about month. A Tuesday in July often beats a Saturday in May on this corridor.
Watch construction holiday as carefully as March Break. Late July leisure seats can firm even when “summer sales” ads are everywhere.
Stack ground wisely. Early YUL departures pair with Montreal airport hotels; late YYZ arrivals favour Pearson or downtown via Trip.com. YUL airport guide covers REM / 747 and terminals.

05 · FAQ
YUL–YYZ cheap calendar FAQ
What is the cheapest month to fly from Montreal to Toronto? +
Many Quebec travellers see softer CAD fares on YUL–YYZ in late January–February (outside long weekends), late April–May, and October–early November. Summer weekends and the December holidays usually cost more. Confirm with a live flexible search.
Are midweek flights cheaper from YUL to YYZ? +
Often yes — and on this ultra-high-frequency domestic hop the Friday/Sunday tax is especially visible. Tuesday–Thursday departures commonly undercut weekend banks. A ±3 day CAD search makes the gap obvious.
How long is the flight from Montreal to Toronto? +
Typical nonstop block time from Montréal–Trudeau (YUL) to Toronto Pearson (YYZ) is about 1 hour 15 minutes to 1 hour 30 minutes airborne. Door-to-door time is dominated by airport process and ground transit, not flight time.
When should I book Montreal to Toronto flights? +
For summer weekends and Christmas, watch 3–8 weeks out. Shoulder midweeks can be more flexible. Fare alerts help when a Leafs/Habs road trip or concert locks your dates.
Should I book flights only or add Toronto hotels? +
Travelpayouts for CAD flights; Trip.com for downtown Toronto, Pearson and Niagara hotels; Redtag.ca if a short city-break package beats building the stay yourself.
