Drive in from Ontario or New England and the car needs somewhere to sleep while you sail — the Port will hold it, by arrangement.
The Port parks cruise passengers at the Grand Quay lot for C$40 a day, taxes included, under a contract you fill in and email before you arrive (grandquai@port-montreal.com, 514-370-7824). The contract form carries no date and lists Visa, Mastercard, debit or cash.
Arrange it by email, not at the barrier — the contract is what earns the flat daily figure.
The Port’s posted rates for the same lot, low season Oct 1, 2026 to Apr 29, 2027: C$25 up to 6 hours, C$30 for 6 to 12, C$40 for 12 to 24 (C$35, C$45 and C$55 from May 1 to Sept 30); the page doesn’t say whether tax is in. Those posted rates stop at a single day, so for a cruise the contract rate is the one that counts — about C$280 for seven days, our arithmetic.
Open 24/7, up to 250 vehicles; maximum height 3 m at the city-side entrance and 3.5 m on the river side; no trailers or motorhomes.
The Old Port’s Clock Tower and King-Edward Pier lots charge by the visit, taxes included, up to C$90 for less than 24 hours, with no multi-day or cruise rate. Seven days billed at that ceiling would be about C$630, our arithmetic. It’s a visit price, not a cruise rate.
When we first read it in September, the Port gave security@port-montreal.com for the contract; by Oct 3, 2026 the page showed grandquai@port-montreal.com. Write to the newer address.
A rental parked for the week is a worse sum. Keep a C$55-a-day car through a seven-night cruise and the rental alone comes to about C$443 with tax, before the lot — hand it back and rent again afterward.
Our Montréal cruise parking page covers the lot in more depth if your own car is the one making the trip.
