A storage unit is a rental contract first and a spare garage second, and what happens when you miss rent is set by an Ontario statute, not by the facility's goodwill.
Self storage in Ottawa comes down to six decisions: how much space you need, what the monthly price includes, whether your belongings need climate control, who insures them, what happens if rent goes unpaid, and when you book. This guide covers each one with public sources, from Ontario's Repair and Storage Liens Act to Canadian Conservation Institute guidance on humidity. It names no facility. Browse the storage listings in Ottawa and put the questions below to each one before you sign.
Key Highlights

TL;DR: No public body publishes an Ottawa self storage price. The most useful public figures are Canada-wide industry averages of CAD $2.37 per square foot for ordinary units and $3.12 for climate-controlled ones. Under Ontario's Repair and Storage Liens Act, a facility cannot sell your goods until 60 days after the amount became due and must give at least 15 days' written notice first. Ask your home insurer in writing whether goods in a rented unit are covered, and book early around late April and the end of June.

Choosing a Self Storage Unit Size in Ottawa

Facilities usually advertise a unit by its floor size, such as 5 by 10 feet, which is 50 square feet of floor. Ask for the ceiling height as well, because boxes stack, and a taller unit holds more than a low one with the same floor area. Sizes and labels are set by each facility, so compare square feet and ceiling height rather than words like "small" or "medium".
Measure instead of guessing. List the large pieces (mattress, sofa, dresser, table, appliances) with their length, width and height, count the boxes, and decide how high you can safely stack them. Leave a walkway to the back wall, and put anything you may need in the next few months near the door. If you land between two sizes, ask whether you can switch units later and whether a fee applies.
Shrink the pile before you rent. Carleton's residences put out donation bins for clean, usable items, and the donations go to the Diabetes Association of Canada. The University of Ottawa runs a Dump and Run program for the same purpose. Our thrift stores guide mentions donation hours and furniture pickup at some Ottawa charity shops, and every box you donate is rent you do not pay.
Self Storage Prices in Ottawa: What the Data Shows

No regulator or public body publishes an Ottawa self storage price, so any single "Ottawa average" you see online comes from a company's own data. The most useful neutral figures come from StorTrack, a firm that tracks facility rates. Its November 2025 review lists Canada-wide averages of CAD $2.37 per square foot for non-climate-controlled space and $3.12 per square foot for climate-controlled space. By those averages, climate control costs about 32 per cent more per square foot.
The page does not say whether those rates are monthly, and it does not break out Ottawa. Unit rents are normally quoted by the month, so confirm that with any facility. As a sense of scale only, a 50-square-foot unit would work out to about $119 (50 × $2.37) or $156 (50 × $3.12) if the figures are monthly. A real quote depends on the facility, the location and the unit.
StorTrack also reports that in December 2025 Canadian walk-in rates were down 1.67 per cent from a year earlier, while online rates were up 0.39 per cent. In other words, the price on a website and the price at the counter can differ, so ask for both and get the one you accept in writing. StorTrack adds that residential moves typically drive storage demand, which is why timing (covered below) can matter as much as the unit.
The same sources give no figures for the extras, so treat these as questions rather than numbers:
- The rate after the first month. Ask whether the advertised price is a promotion, how long it lasts and what the unit costs afterwards.
- One-time charges. Ask about an administration fee, a lock, a deposit and any charge to reserve a unit.
- Tax and insurance. Ask whether the quote includes the 13 per cent HST, and whether the facility requires you to buy its protection plan.
- Rent changes. Ask how often the rent can rise and how much written notice you get.
Climate-Controlled Storage for Ottawa Winters and Summers

"Climate controlled" can mean heated, cooled, humidity controlled or only that the unit sits inside a heated building. Ask which one, and what range the facility holds in January and in July. The Canadian Conservation Institute (CCI), part of the federal government, writes for museums, but the physics applies to a grandmother's dresser just as well.
Summer risk is damp. CCI defines damp as relative humidity (RH) above 75 per cent and says it causes mould and rapid corrosion of metals. Clean plant-based materials such as wood, cloth and paper usually need about 80 to 85 per cent RH before mould is likely, while leather, and anything starched or dirty, can grow visible mould at lower levels: CCI puts it at about 100 days at 70 per cent RH. CCI also notes that in hot, humid weather, outdoor air touching floors or walls a few degrees cooler forms damp.
Winter risk is the opposite. CCI explains that cold outdoor air holds very little moisture, so air at 0°C and 50 per cent RH becomes about 11 per cent RH once it is heated to 20°C. In many parts of Canada, indoor RH can drop as low as 5 per cent by December when a building is heated to 21°C without humidifying. That creates a high risk of cracking for furniture, especially glued, veneered or inlaid pieces. The risk applies only if the dry air lasts long enough, since most furniture takes many days or even months to respond fully.
Swings can also do harm. CCI's tables list wood furniture, instruments, photographs, paintings, books and paper, leather and old magnetic tape among the things damaged by incorrect humidity. Stacked photographic prints can stick together in damp air. Whatever unit you rent, follow CCI's storage basics: keep items off the floor on shelves, pallets or blocks, cover them loosely with plastic sheeting, make sure air can circulate and keep food out. CCI also says basements and attics are usually poor places to store collections because of temperature swings, extreme humidity and leaks, which is worth remembering if the alternative is your own basement.
Prohibited Items and Contract Terms to Read

Every agreement has its own list of banned goods, so read it before you pack. Expect fire hazards and hazardous products to be on it. CCI's advice for its own storage rooms is a useful hint: do not keep flammable materials such as solvents, paints, varnishes or waxes in or near them, and keep food and drink out. The City of Ottawa treats paint, aerosols, solvents, pesticides, pool chemicals, adhesives, household cleaners, light bulbs and tubes, batteries and small propane cylinders as household hazardous waste, so none of it belongs in a unit anyway.
The City says residents do not have to wait for a collection event: its Waste Explorer tool points to retailers that take back light bulbs, batteries, paint and oil daily. Its 2026 events listed October 17 at the Strandherd Snow Dump (4061 Strandherd Drive, 8 a.m. to 4 p.m., entering from Philsar Street) and November 7 at the Westbrook Snow Dump (200 Westbrook Road, 8 a.m. to 4 p.m.). Containers over 20 litres are not accepted and the service is for Ottawa residents only, so check the City's household hazardous waste page before you go.
Then read the rest of the contract with a pen in hand. These are the terms that tend to cause disputes:
- Term and notice. Is it month-to-month or fixed, how much notice ends it, and do you pay for the whole month if you leave early?
- The price. Does the rent include HST, fees and insurance, and when and by how much can it rise?
- Access. What are the gate hours, including holidays, and how can access be cut off if you are late?
- Late fees and default. When can the facility deny access and start the sale process, and how will it contact you? Keep your mailing address current (see the lien section below).
- Liability. Does the agreement limit what the facility pays if goods are damaged or stolen, and does it say who enters the unit and when?
- Abandoned goods. One Ottawa law firm's explainer for facility owners notes that the Act does not address goods left behind when a contract ends for a reason other than unpaid rent, or simply expires, so contracts often say such goods are deemed abandoned. Read that clause closely.
Insuring Stored Goods: Home Policy or Facility Plan

You have two questions to settle: does your own policy cover goods in a rented unit across town, and what does the facility's plan actually cover? The Insurance Bureau of Canada (IBC) says tenant insurance covers your possessions in your apartment "and while you're away," and that a condo owner's policy typically covers personal property including items kept in a locker. It adds that contents can be insured on an "all risks" basis or for named perils only. The pages I read do not say how a policy treats goods in a rented unit at another address, so do not assume it does.
Ask your broker or insurer these questions, and ask for the answers in writing:
- Is off-premises storage covered, and up to what limit? Ask for the number and compare it with the value of what you are storing.
- Which perils are covered? Check whether theft, fire and water damage are included or whether only named perils apply.
- Are there limits on valuables? Ask whether jewellery, art, collectibles or electronics have their own, lower limits.
- What about water? IBC lists sewer backup and overland water as optional coverages. If a unit floods, ask whether yours would respond.
- Do you have to tell the insurer? Ask whether a long-term unit needs to be reported and whether anything changes after a set period.
Then do the same for the facility's plan. Ask for the policy wording, not a brochure. Find out who the insurer is, what perils it covers, the limit per item and in total, the deductible and whether claims pay replacement value or depreciated value. If the facility requires you to buy its plan, you still need to know what it does and does not pay for before you rely on it.
Keep a dated photo or video of everything, receipts for the big items, and a copy of the inventory somewhere other than the unit. Water was the big hazard this summer. After the July 1, 2026 storm, the mayor said nearly 5,800 residents had reported flooded basements to the City, according to the Ottawa Citizen. Our car and home insurance guide explains sewer backup and overland flood cover in plain terms.
What Ontario's Repair and Storage Liens Act Allows When Rent Goes Unpaid

An Ottawa law firm's explainer says storage unit rentals in Ontario are governed by the Repair and Storage Liens Act (RSLA), not the Commercial Tenancies Act. The statute gives a storer a lien, a legal claim on the goods for the amount agreed for storage, and lets it keep the goods until that is paid. The table below summarizes what the current text says. This is a plain-language summary, not legal advice, and your contract may add terms.
| Step | What the Act says | Section |
|---|---|---|
| The claim | The lien arises when the facility receives the goods and covers the agreed storage charge. It may keep the goods until paid | 4 (1), (3) |
| Earliest sale | The right to sell starts after 60 days from the day the amount became due | 4 (7) |
| Written notice | At least 15 days before a sale, in writing, to the person who left the goods, the owner if different, and registered secured creditors | 15 (2) |
| What the notice must say | A description of the goods, the amount owing, how daily storage costs are calculated, that you can redeem by paying, where and when, the date, time and place of a public sale or the date after which a private sale may occur, and that the goods may be sold unless redeemed | 15 (3) |
| How it is delivered | In person, or by registered or certified mail or prepaid courier to the last known mailing address. It counts as given on the day you receive it or the tenth day after it is sent, whichever is earlier | 27 |
| The sale | May be public or private, but every aspect must be commercially reasonable. The facility may buy only at a public sale | 15 (4), (5) |
| The proceeds | Applied first to the expenses of sale and seizure, then the facility's lien and other registered claims, then to the owner if the facility knows of their claim | 16 |
| Keeping the goods | The facility may propose to keep them instead. You have 30 days to object in writing | 17 |
| Giving to charity | Allowed only after the facility has held the goods for 12 months after the right to sell arose, if they are worth less than the debt and expenses, and no sale or retention notice was given | 19 |
| Redeeming | You may redeem by paying the amount needed to satisfy the lien at any time before the sale is contracted, the facility retains the goods or they go to charity | 22 |
Three further points matter. First, a sale or retention is treated as full satisfaction of the lien amount, so the facility cannot use the lien to chase a shortfall afterwards (section 18). Second, a buyer who purchases in good faith in a sale keeps the goods even if the facility broke the rules, so your remedy is against the facility: it owes the greater of $200 or your actual damages, and any person can apply to a court to settle their rights (sections 20, 21 and 23). Third, a facility may add its commercially reasonable costs of storing and preparing the goods for sale to the amount you owe, but the Act gives it no lien for interest, though that does not stop it recovering interest in other ways (section 28).
The practical lesson is that the notice goes to the address on file. Update your mailing address in writing if you move, open mail from the facility promptly, and ask for an itemized statement if a number looks wrong. If you cannot pay, ask for a payment plan in writing before the 60 days run. For legal advice, see our guide to free legal help in Ottawa.
Timing: April Move-Out, July 1 and Booking Ahead

University residences set hard dates. Carleton required residents to vacate 24 hours after their last exam or by noon on Friday, April 24, 2026, whichever came first. For 2027, its calendar has students with no exams or take-home assignments leave by noon on April 11, everyone else leave 24 hours after their last exam between April 11 and April 24, and a final check-out at noon on April 24 with no extensions. The University of Ottawa's end-of-year move-out for its main residence buildings is May 1, 2026 at 9 a.m., and May 3, 2027 at 9 a.m.
The University of Ottawa tells residents to confirm accommodation, transport or storage two to three weeks before move-out and says it is not responsible for items left behind. Off-campus leases end on their own dates, and our Ottawa rental guide covers tenant rights around them. The practical rule: if you need a unit for May to August, book it as soon as your move-out date is known, then ask about the minimum term and whether the first and last months are pro-rated.
No public source gives monthly occupancy for Ottawa facilities, so I cannot say how full they get. StorTrack's point that residential moves drive demand is a reason to ask early, not a measurement.
July 1 is a different pressure. In Quebec, July 1 is the traditional Moving Day, when most leases begin and end, though Wikipedia notes that this is a tradition and not a legal requirement. Gatineau sits across the river from Ottawa. I could not find public data on how much of that tradition reaches Ottawa facilities, but it is one more reason to book ahead for the end of June. July 1 is also Canada Day, one of Ontario's nine public holidays, so ask whether the office is staffed, what the gate hours are and whether you can sign up and collect a key or code online beforehand. Our Canada Day guide covers the downtown road closures.
FAQ
Q: How much does self storage cost in Ottawa?
No public body publishes an Ottawa figure. StorTrack's 2025 Canada-wide averages are $2.37 per square foot for non-climate-controlled units and $3.12 for climate-controlled ones, with no period or Ottawa breakout stated. Ask each facility for the full cost, including fees, HST and insurance, and for any rate change after the first month.
Q: Do I need a climate-controlled unit in Ottawa?
It depends on what you store. The Canadian Conservation Institute says damp above 75 per cent humidity causes mould and corrosion, and heated winter air can fall to 5 per cent humidity and crack furniture. Wood, leather, paper, photographs and instruments are most at risk. Ask what the facility actually controls.
Q: Does my home insurance cover a storage unit?
Not necessarily. The Insurance Bureau of Canada says tenant policies cover possessions in your home and while you are away, and condo policies typically cover items in a locker, but its pages do not address a rented unit elsewhere. Ask your insurer in writing about limits, covered perils and valuables.
Q: How long before a storage facility can sell my belongings in Ontario?
Under the Repair and Storage Liens Act, the right to sell begins 60 days after the amount became due, and the facility must give written notice at least 15 days before a sale. You can redeem the goods by paying what is owed at any time before the sale. This is a summary, not legal advice.
Q: What can't I put in a storage unit?
Your agreement decides. Expect flammables and hazardous goods to be banned. The City of Ottawa classes paint, aerosols, solvents, pesticides, pool chemicals, batteries and small propane cylinders as household hazardous waste, and its Waste Explorer lists retailers that take back batteries, paint and oil. Ask the facility in writing about food, vehicles and anything unusual.
Q: When should I book storage for the student move-out?
As soon as your move-out date is known. Carleton's final residence check-out is noon on April 24, 2027, and the University of Ottawa's is May 3, 2027, at 9 a.m. The University of Ottawa suggests confirming storage two to three weeks ahead. No public data shows how full Ottawa units get, so booking early is a precaution.
Final Thoughts
A storage unit works well when you treat the agreement as seriously as the key. Measure before you rent, compare the full monthly cost including HST and fees, and ask what "climate controlled" means in a January cold snap and a humid July. Get your insurer's answer on off-site goods in writing, and do the same for the facility's plan.
Keep your mailing address current, because the law ties the notice clock to it. Book ahead around late April and the end of June. When you are ready to compare facilities, start with the Storage directory page and check each operator's current terms yourself.
