Let me break down one of the most common questions I get from business owners looking for commercial mortgage financing: should you go with a big bank or a credit union?
It’s not as simple as saying one is better than the other. The answer depends on your situation, your property, and what you’re trying to accomplish. Let me walk you through the real differences so you can make an informed decision.
The Big Bank Advantage
The big banks in Canada—TD, RBC, BMO, Scotiabank, CIBC—have some clear advantages when it comes to commercial mortgages.
First, they have deep pockets. If you’re looking at a $5 million warehouse purchase or a $10 million apartment building, big banks can write these cheques without blinking. Credit unions typically have lending limits that might cap out at $2-3 million for commercial deals, though this varies by institution.
Second, big banks offer relationship banking. If you already have your operating accounts, business line of credit, and personal banking with TD, for example, consolidating your commercial mortgage there can streamline your banking. Some clients appreciate having everything in one place.
Third, big banks have sophisticated products. Need a construction loan with multiple advances? Want to hedge your interest rate risk with derivatives? Looking for international banking services? Big banks have these capabilities built out.
The rates can also be competitive, especially if you’re a strong borrower with good credit, solid financials, and a conventional property type. For a straightforward office building purchase with 35% down and strong rent rolls, big banks will compete aggressively on rate.
Where Big Banks Fall Short
Here’s the thing though. Big banks are bureaucratic. The decision-making process involves multiple layers, credit committees, and rigid underwriting criteria. If your deal has any complexity or doesn’t fit their standard boxes, you’ll struggle.
I’ve seen big banks turn down perfectly good deals because the property was too small (they don’t want to bother with a $500,000 deal), too rural (no comparables in their system), or involved a business type they don’t understand (self-storage, marinas, mixed-use properties with unique tenants).
Big banks also focus heavily on your personal covenant. They want to see strong personal credit scores, substantial net worth, and proven business experience. If you’re a first-time commercial borrower or you’ve had some credit bumps in the past, big banks become very difficult to work with.
The approval process is slow. Count on 4-6 weeks minimum, often longer if there are any questions or unusual aspects to your deal. I’ve seen big bank approvals take 12 weeks for deals that a credit union approved in 3 weeks.
The Credit Union Difference
Credit unions operate differently. They’re member-owned institutions that serve specific communities or regions. In 2026, credit unions like Meridian, Coast Capital, Conexus, and dozens of regional credit unions across Canada are major players in commercial lending.
The biggest advantage? Relationship-driven decision making. Credit unions empower their local commercial lenders to make decisions. Your application gets reviewed by people who understand your local market and can use common sense alongside the underwriting criteria.
I had a client buying a small commercial building in rural Saskatchewan. The property was a mixed-use building with retail on the main floor and apartments above—not a conventional property type. The big banks said no because they couldn’t get comfortable with the rural location and mixed-use nature.
The local credit union knew the town, knew the market, and understood that this type of building was common and stable in that community. They approved the deal in three weeks at a competitive rate.
Credit unions are also more flexible on structure. Need a longer amortization? Willing to negotiate on prepayment penalties? Want to structure a deal with graduated payments? Credit unions have more flexibility to customize the terms to fit your situation.
The relationship aspect matters beyond the initial approval too. When you need to discuss cash management, business accounts, or future financing needs, you’re dealing with a local team that knows you, not a call center in Toronto.
The Trade-offs with Credit Unions
Credit unions have limitations you need to understand.
First, lending limits. If you’re buying a $5 million property, many credit unions simply can’t do the deal. Their internal limits or regulatory constraints cap them at lower amounts. Some credit unions can go higher through syndication with other credit unions, but it adds complexity.
Second, geographic restrictions. Credit unions serve specific regions or member groups. If you’re in Vancouver, you can’t just waltz into a Saskatchewan credit union and get a loan. You need to be in their service area or become a member through specific criteria.
Third, product sophistication. Credit unions may not offer the complex products that big banks provide—things like interest rate swaps, multi-currency accounts, or sophisticated construction financing with cost-to-complete analysis.
Fourth, rates aren’t always better. People assume credit unions always beat big bank rates, but that’s not true. For standard deals with strong borrowers, big banks can be very competitive. Credit unions shine when your deal has complexity that big banks reject—you’re paying a bit more for the flexibility and willingness to say yes.
Real-World Examples
Let me give you some scenarios to make this concrete.
Scenario 1: $3 million industrial building in Mississauga
Strong borrower with 700+ credit score, 35% down payment, established business with solid financials. The property is 100% leased to creditworthy tenants on long-term leases.
Best fit: Big bank. This is a textbook deal. Big banks will compete on rate, probably getting you into the 5.5-6.0% range (2026 rates) with standard terms. No reason to overcomplicate it.
Scenario 2: $1.2 million mixed-use building in Kelowna
Good borrower, 25% down payment, property has retail on the main floor and four residential units above. Some deferred maintenance that you’ll address over time.
Best fit: Credit union. Big banks will struggle with the mixed-use nature and smaller size. A BC credit union will understand this property type, be comfortable with the market, and approve it without drama.
Scenario 3: $8 million apartment building in Edmonton
Strong borrower looking for long-term financing, wants to lock in a 10-year term, needs CMHC insurance to get high-ratio financing.
Best fit: Big bank. The size requires big bank capacity, and big banks are active in the CMHC-insured space. They have the resources to handle CMHC applications and the appetite for larger apartment deals.
Scenario 4: $600,000 warehouse in rural Manitoba
Borrower has okay credit (650 score), 30% down payment, buying the building for their existing business that’s been operating successfully for 15 years.
Best fit: Credit union. Big banks won’t touch this—too small, too rural, credit score is below their comfort zone. A local Manitoba credit union will look at the overall story, understand the business, and approve it based on the full picture.
The Hybrid Approach
Here’s something many business owners don’t consider: you can use both.
I have clients who keep their operating accounts and day-to-day banking at a big bank because they like the online systems, ATM access, and integration with their accounting software. But they get their commercial mortgages through credit unions because the rates or flexibility are better for their property types.
There’s no rule that says everything has to be at one institution. In fact, diversifying your banking relationships can be smart. If one lender decides to pull back on your industry or tighten credit, having relationships with multiple institutions gives you options.
What About Rate?
Let’s talk numbers, because that’s what everyone wants to know.
In 2026, for a standard commercial mortgage on a conventional property with a strong borrower:
- Big banks: 5.5-6.5% for 5-year terms
- Credit unions: 5.75-6.75% for 5-year terms
Credit unions are often 25-50 basis points higher than big banks on apples-to-apples deals. But that spread narrows or disappears when your deal has complexity, because big banks often just say no rather than pricing for the additional risk.
The rate matters, obviously. But it’s not the only factor. A credit union that approves your deal at 6.5% is infinitely better than a big bank that offers 6.0% but then declines you after a 6-week process.
Making Your Decision
Here’s how to think about which way to go:
Go with a big bank if:
- Your deal is large (over $3 million)
- The property type is conventional (office, retail, industrial, apartment)
- You’re a strong borrower with excellent credit and financials
- You value product sophistication and relationship banking
- Speed isn’t critical
Go with a credit union if:
- Your deal is smaller (under $2 million)
- The property has unique characteristics
- You’re in a smaller community or rural area
- You value relationship lending and local decision-making
- You need flexibility on structure or terms
- Your credit or financial situation has some challenges but the overall story is strong
The Broker Advantage
Here’s why working with a mortgage broker like Creek Road Financial Inc. makes sense for this decision.
We’re not loyal to any one lender. Our job is to understand your situation and match you with the right financing source. Sometimes that’s a big bank, sometimes it’s a credit union, sometimes it’s an alternative lender entirely.
We also know which specific credit unions or bank branches are active in your property type and region. Not all big bank branches have the same appetite, and not all credit unions focus on the same types of deals. We know who’s lending on what.
Plus, we can run your deal past multiple lenders simultaneously. Instead of you applying to TD, waiting 6 weeks, getting declined, then starting over with a credit union, we present your deal to several options at once and see who bites.
The Bottom Line
Big banks and credit unions both have their place in commercial mortgage financing. The right choice depends on your deal specifics, your borrower profile, and what you value most.
Big banks bring capacity, product sophistication, and competitive rates for conventional deals. Credit unions bring flexibility, relationship lending, and common-sense decision making for deals that don’t fit the standard mold.
Often, the best approach is to let a broker evaluate your situation and recommend the path that makes most sense. We’ve placed thousands of commercial mortgages with both big banks and credit unions, and we know how to position your deal for success with each type of lender.
