Condo mortgage rules in Canada: what buyers need to know
How condo fees affect your qualification, what lenders look for in a condo building, pre-construction risks, and the status certificate explained.
Buying a condo in Canada involves a set of mortgage rules that are meaningfully different from buying a detached house. Condo fees directly affect how much mortgage you qualify for, lenders scrutinize the condo corporation's finances before approving your mortgage, and certain types of condos face restrictions that can make financing difficult or impossible. This guide covers everything you need to know about condo mortgages in Canada before you make an offer.
How condo fees affect your mortgage qualification
This is the most important difference between a condo and a house mortgage. In Canada, lenders include 50% of your monthly condo fees in your Gross Debt Service (GDS) ratio calculation.
Why this matters: Every $500/month in condo fees reduces your maximum mortgage by approximately $50,000-$75,000. High condo fees are one of the most common reasons condo buyers qualify for less than they expected.
Example
- Buyer income: $100,000/year
- No existing debts
- Without condo fees: maximum mortgage approximately $470,000
- With $800/month condo fees: 50% = $400 added to GDS → maximum mortgage reduced to approximately $375,000
- The $800/month condo fee cost this buyer $95,000 in borrowing power
Practical implication: When comparing a $600,000 condo with $700/month fees versus a $650,000 house with no fees, the house may actually be easier to qualify for despite the higher price. See our affordability guide for the full GDS/TDS math.
What lenders look for in a condo building
Unlike a house where the lender only evaluates you and the property, condo mortgages involve a third party — the condo corporation. Lenders assess the financial health and characteristics of the entire building before approving your mortgage.
Reserve fund adequacy
The condo corporation's reserve fund is a pool of money set aside for major repairs — roof replacement, elevator maintenance, parking structure repairs. Lenders want to see a healthy reserve fund because an underfunded reserve fund leads to special assessments — unexpected large bills to all unit owners.
What to check: Request the most recent reserve fund study. A well-funded reserve has at least 70-100% of the recommended amount. Below 50% is a red flag.
Owner-occupancy ratio
Lenders prefer buildings where most units are owner-occupied rather than rented out. Most major Canadian lenders require at least 50% owner-occupancy. Buildings with high investor ownership and rental units are considered higher risk.
Buildings marketed primarily as investment properties or short-term rental buildings (sometimes called "condo hotels") face severe financing restrictions — many lenders will not finance these at all.
No single entity owning too many units
If one investor or company owns more than 10-20% of the units in a building, many lenders will decline to finance purchases in that building. Concentrated ownership creates risk if that owner defaults or stops paying fees.
No ongoing litigation
If the condo corporation is involved in significant litigation — suing the developer for construction defects is common — lenders may decline or require special conditions. Active litigation creates financial uncertainty for the corporation.
Commercial space ratio
Buildings with significant commercial space on lower floors (retail, restaurants, offices) may face restrictions from some lenders. Generally buildings with more than 25-35% commercial space can be harder to finance.
New condo vs resale condo — different rules
Pre-construction condo mortgages
Buying a pre-construction condo (before it is built) involves unique risks and rules:
- Deposit structure: Developers typically require 15-25% in deposits paid over the construction period — not at closing. These deposits are protected by provincial legislation (Tarion in Ontario, HPO in BC) but only up to certain limits.
- Rate hold challenge: Your mortgage is not arranged until closing — which may be 2-5 years away. The rate environment at closing may be very different from when you signed. You cannot lock in a mortgage rate for 5 years in advance.
- Assignment risk: If you need to sell before closing (assignment sale), the rules are complex and tax implications are significant.
- Occupancy fees: In Ontario, there is often a period between when you move in and when the building is registered as a condo. During this "interim occupancy" period you pay occupancy fees to the developer rather than mortgage payments.
Resale condo mortgages
Resale condos follow standard mortgage rules with the additional building-level checks described above. The key advantage is you can review the actual condo corporation documents — status certificate, reserve fund study, meeting minutes — before committing.
Always review the status certificate before removing your financing condition. The status certificate reveals special assessments, litigation, financial position, and any rules that affect your unit.
The status certificate — your most important document
The status certificate is a document prepared by the condo corporation that summarizes the financial and legal status of both the corporation and your specific unit. In Ontario it costs $100 and the corporation has 10 days to provide it.
Always have a real estate lawyer review the status certificate before removing your financing condition. Key things to look for:
- Common expenses (condo fees): Confirm the amount and whether any increases are planned
- Special assessments: Any upcoming or recently levied special charges against all unit owners
- Arrears: Whether the previous owner owes any unpaid condo fees (you may inherit these)
- Reserve fund balance: The current balance and whether it is adequately funded
- Litigation: Any active lawsuits involving the corporation
- Rules and restrictions: Pet restrictions, rental restrictions, renovation rules, parking rules
- Budget: The corporation's annual budget and whether it is running a surplus or deficit
Condo types that are hard or impossible to finance
Condo hotels and resort properties
Units in buildings operated as hotels — where units are rented out through a rental pool managed by the hotel operator — are treated as commercial properties by most lenders. Standard residential mortgages are typically not available. These require commercial financing at higher rates with larger down payments.
Micro condos (under 400 square feet)
Some lenders have minimum size requirements for condo financing. Units under 400-500 square feet may be declined by major banks. Alternative lenders may finance them but at higher rates. Always confirm with your lender before making an offer on a very small unit.
Buildings with major structural issues
If a building has known major structural defects, water infiltration problems, or envelope issues, lenders may decline to finance units in that building until repairs are completed.
High investor concentration buildings
Buildings where the developer retained many units as rentals or where one investor owns many units face financing restrictions as described above.
Down payment rules for condos
The same minimum down payment rules apply to condos as houses:
- Under $500,000: minimum 5% down
- $500,000 to $1,499,999: 5% on first $500,000 + 10% on remainder
- $1,500,000+: minimum 20% down
CMHC insurance is available for condos with less than 20% down — subject to the building meeting CMHC's eligibility requirements (owner-occupancy ratios, reserve fund, no major litigation). See our minimum down payment guide for the full 2025 rules.

Do condo fees include property tax?
No. Property tax is separate and paid by you directly — either as part of your mortgage payment (collected by lender in trust) or directly to the municipality. Condo fees cover building maintenance, insurance for common areas, amenities, management, and reserve fund contributions.
Can I rent out my condo?
It depends on the condo corporation's rules. Some buildings have rental restrictions — maximum percentage of units that can be rented, minimum lease terms, or outright bans on short-term rentals. Check the status certificate and condo declaration before purchasing if you plan to rent.
What happens if the condo corporation runs out of money?
The corporation levies a special assessment — a one-time charge to all unit owners to cover the shortfall. Special assessments can range from a few hundred dollars to tens of thousands per unit. This is why reviewing the reserve fund study is so important before buying.
Are condo fees going up in Canada?
Yes — significantly in many buildings. Rising insurance costs, aging buildings requiring more maintenance, and inflation in labour and materials have driven condo fee increases of 10-30% or more in some buildings over the past 3 years. Always ask about the history of fee increases when reviewing a condo purchase.
Can I get a mortgage for a condo I plan to use as an Airbnb?
Most lenders require the property to be used as your primary residence or a traditional long-term rental for standard mortgage financing. Purchasing with the explicit intent to operate as a short-term rental and misrepresenting this to your lender constitutes mortgage fraud. Additionally most condo corporations now prohibit Airbnb and other short-term rentals.
What is the difference between a condo and a townhouse for mortgage purposes?
It depends on how the property is legally structured. A freehold townhouse (you own the land and building) is treated like a house — no condo fee impact on GDS. A condo townhouse (part of a condo corporation) is treated like a condo — 50% of fees included in GDS. Check the legal status of any townhouse you are considering.
