Should You Rent a Car for a Montréal Cruise?

Montréal’s ships often start here and finish somewhere else — Boston, New York or Florida among them. That turns a rental into a one-way, and the Québec City page covers the pairing a car handles best.

Spend the night before downtown and the ship is a short cab away, not a drive. A car only adds a parking bill to that night.

The Port names Square-Victoria and Place-d’Armes as the nearest métro stations.

We didn’t time the walk from the quay to either one — leave room for bags, and for the slope up from the river.

From the airport, the STM’s 747 is the car-free default — and its ticket doubles as a day of métro rides. The YUL page has the fare and the catch at the downtown end.

The REM doesn’t reach the airport yet: REM says the YUL branch is scheduled for 2027, and Time Out reported in August 2026 that testing had begun, with the stations due at the end of 2027.

So for a 2026 sailing the new light rail is a city line, not an airport answer.

Until Oct 19, 2026, the STM’s temporary route 815 links YUL to the REM’s Des Sources station.

It adds a transfer and ends before the cruise season does — we wouldn’t build a boarding day around it.

A cab from YUL runs at a flat fare that the Port says covers the Grand Quay; the airport page sets it against a one-day car.

Uber and Lyft work the airport as well. Open the app before you decide — no fare is published, and Tourisme Montréal says demand moves it.

Inside the old city, walk. The Old Port’s own lots charge by the visit, up to C$90 for under 24 hours, and the hub has the Port’s cruise rate.

Right turns on red are allowed everywhere in Québec except on the island of Montréal, and wherever a sign forbids them; the Grand Quay, downtown and YUL are all on the island.

Most American drivers turn right on red by reflex.

On the island that reflex breaks the law, so wait for the green even on an empty street.

Regulatory signs are in French: “Arrêt” is stop, “Cédez” is yield.

The shapes and colours are the ones you know, so the octagon still means what it always meant.

Distances and speed limits are in kilometres. A 100 on a sign is roughly 62 mph, our conversion.

Québec-registered vehicles, rentals included, need winter tires from Dec 1 to Mar 15 (fine C$200 to C$300); cars registered elsewhere are exempt. Montréal’s cruise season ends Oct 31, so a cruise rental falls outside the rule.

So the winter-tire law won’t touch a cruise rental. The tire-management fee on an Avis quote is a cost recovery, not a sign you’re getting winter tires — the hub’s tax section lists it with the other fees.

Québec law: children ride in a seat suited to their weight and height until they are 9 or at least 145 cm (4 ft 9 in) tall; the fine is C$80 to C$100 and 3 demerit points.

As we read the SAAQ page, whichever comes first frees the child from the seat. Confirm on the page itself if you’re near either line.

We found no Canadian car-seat price, so the calculator uses Avis’s published US figure, $14 a day up to $84 a rental, typed in as C$.

On that figure, two rented boosters for a three-day car are about C$84, our arithmetic. Bring your own if you’re flying with them anyway.

Count suitcases before seats.

Enterprise lists a midsize car at three bags, a couple’s cruise luggage rather than a family’s — so size up when the bags are in doubt.

The split is about distance, not taste. One downtown day costs about C$63 at an assumed C$55 with tax — fine for a trip out of town, and dear for a car that never leaves the grid.

Book it for that day alone — and return it the same evening.

If the taps came back “rent,” book the car for the out-of-town day alone. Collect it in the morning and return it before the desk closes.

Downtown counters close early on weekends, so read the hub’s hours checker before you choose the return time.
