A 10×10 storage unit in Montreal runs anywhere from about $120 to $235 a month depending on where and what you rent, and the difference over a year is more than a thousand dollars for the same empty square. Around July 1, when most Quebec leases end at once, the calculus gets worse: the convenient units are gone weeks before moving day. Here is what storage actually costs in Montreal in 2026, and which companies are worth calling first.
How much does self-storage cost in Montreal in 2026?
Across 41 Montreal facilities tracked by the aggregator FindStorageFast, the averages are $69 a month for a 5×5, $138 for a 5×10 and $231 for a 10×10. The WantStorage Canadian pricing index from May 2026 reads lower for the 10×10 at $189 across 23 tracked facilities, and operators’ own guides quote $120 and up. The spread is the point: identical sizes vary by neighbourhood, floor and building age, and climate control adds roughly 15 to 20 percent. Downtown and Plateau-adjacent buildings price highest; industrial-zone facilities in Saint-Léonard, Anjou or LaSalle price lowest.
The best self-storage companies in Montreal
1. Montreal Mini-Storage: best island coverage
The largest local chain, with 24 locations spanning Ahuntsic, Ville Saint-Laurent, Parc-Extension, Mile-Ex, NDG, Saint-Léonard, Ville-Marie, Saint-Henri, Hochelaga, Anjou, LaSalle and Lachine, plus Laval and the South Shore. Published unit ranges start in the tens of dollars for the smallest lockers and top out around $235 for large units, with a running promotion of 50 percent off up to 6 months. Heated units, drive-up access, no long-term commitment, and a 4.9-star rating displayed on its own site. If you want storage close to home, this is usually the shortest drive.
2. Depotium Mini-Entrepôt: biggest network, moving-van perk
Depotium is the Quebec brand of StorageVault Canada, with 18-plus Montreal locations including downtown on Saint-Paul West, Griffintown and Montreal North. The standing offer is 4 weeks free on select units plus a free moving van at move-in, which quietly saves a truck rental. Downtown, small units list from around $100 a month. Climate control, drive-in loading bays and parcel acceptance are standard at the flagship locations. Note that Access Storage’s Montreal pages redirect here: in this market they are the same company.
3. Public Storage Canada: lowest published 5×5
Five Montreal facilities, including Côte-de-Liesse, Iberville and Métropolitain East, with 5×5 units published from $69 a month at Côte-de-Liesse. Promotions favour commitment: 50 percent off when you rent for three months, a half-price seventh month after six, or a free extra month on a 12-month term. Access 365 days a year, drive-up at most locations, free dollies on site.
4. U-Haul: best if you are already renting their truck
Eighteen locations serving Montreal, with the downtown Cité 2000 facility on Notre-Dame East listing a 5×5 at $89.95 to $94.95 and a 5×10 at $129.95 to $139.95. The month of free storage requires a truck or trailer reservation, which is exactly when most people need storage anyway, and the 1-year price lock plus no deposit and no admin fee make the invoice predictable. Access runs 5 a.m. to 10 p.m. daily rather than 24/7.
5. StorageMart: downtown value
Three Montreal-area buildings: Griffintown on Rue du Shannon from $47 a month, Saint-Léonard from $32, and Saint-Hubert on the South Shore from $11 a week. Drive-in loading bays and climate-controlled indoor units, with discounts applied to the move-in month. For downtown proximity at a published sub-$50 entry price, nothing else on this list matches it.
6. SmartStop Self Storage: the new entrant
SmartStop opened its first Quebec facilities in 2025 and now lists locations on Notre-Dame West and in Dorval. Current offers stack up to 50 percent off plus a free first month on select units, with up to 25 percent off for booking online. Climate control on select units, video surveillance and online account management. New buildings chasing occupancy are where promo math tends to be most generous.
7. Cubeit and GoCube: storage that comes to you
Portable storage flips the model: a container is dropped at your address, you load it, and it is stored in a monitored warehouse. Cubeit, another StorageVault brand, serves Montreal from Vaudreuil-Dorion with 8×16-foot containers from about $7 a day for temporary use, and displays a 4.8 Google average across 5,029 reviews company-wide. GoCube, a Montreal local, quotes from about $95 a month with a 2,000-pound capacity per cube and a heated, 24/7-monitored warehouse. For a July 1 lease gap, a loaded container beats moving everything twice.
How to choose, in four checks
First, compare the regular rate, not the promo, because the promo lasts weeks and the lease runs months. Second, confirm insurance: most facilities require proof of coverage or sell their own tenant policy, and that line item changes the real monthly cost. Third, match climate control to what you store; furniture and electronics want it through a Montreal winter, a bicycle does not, and skipping it saves that 15 to 20 percent. Fourth, check access hours against your schedule, since not every building is 24/7. And before renting a single cubic foot, price what you are storing: our Montreal junk removal cost guide exists because a $150 pickup is sometimes smarter than $1,500 a year of storing furniture nobody will use again.
Quick answers
How much does a storage unit cost in Montreal in 2026?
Aggregator data across 41 Montreal facilities puts the average 5×5 unit around $69 per month, a 5×10 around $138, and a 10×10 anywhere from about $120 to $235 depending on the location and building. Climate control typically adds a 15 to 20 percent premium. Promo rates run far lower, sometimes under $20 for the first weeks, so the number to compare is always the regular rate after the promo ends.
Why does Montreal storage fill up around July 1?
Most Quebec residential leases end June 30, so the city moves at once, an estimated 100,000-plus people in a single day by the Montreal Gazette’s count. Anyone whose new lease starts later than the old one ends needs somewhere to put a full apartment for days or weeks, and the units near dense rental neighbourhoods go first. Book weeks ahead if your move lands anywhere near July 1.
Are the first-month-free storage promos real?
Real, but conditional. U-Haul’s free month requires a truck or trailer reservation. Depotium’s four free weeks apply to select units. StorageMart discounts only the move-in month. The promo gets you in the door; the regular monthly rate is what you actually live with, so compare that number across facilities before signing.
Storage is usually one leg of a bigger move. The 30-day moving checklist tells you when to book the unit relative to everything else, and the 2026 Montreal moving cost guide covers what the movers hauling it all should charge.
