The Canadian mortgage market is not banks and then a cliff. It is a graded set of lenders with different funding, different regulation and different risk appetites, and a file that does not fit one tier often fits the next one comfortably.
Tier one: A lenders
The large banks, plus the monoline lenders most people have never heard of, such as First National, MCAP and CMLS. Monolines do nothing but mortgages, have no branches, and fund an enormous share of Canadian lending. They are not a lesser option; they frequently price better than the banks and are only accessible through brokers.
Alongside them sit credit unions, which are provincially regulated. That matters, because they are not bound by the federal stress test in the same way on uninsured lending, which gives them genuine latitude. In Alberta they are often the best home for a self-employed or variable-income file.
Who they lend to: credit above roughly 600 and ideally 680, documentable income, ratios inside thirty-nine and forty-four percent, standard property.
Cost: the best rates available, no lender fee.
Tier two: B lenders and alternative lenders
Trust companies, some credit unions, and specialist institutions such as Equitable Bank, Home Trust, Haventree and Community Trust. Regulated, legitimate businesses that many people wrongly assume are disreputable.
They exist because the A tier's rules exclude a large population of perfectly good borrowers: the self-employed whose returns understate their income, people with a recent credit event, newcomers, and anyone whose income is real but awkward to document.
They will look at bank deposits instead of tax returns, accept a lower score, and read a file rather than scoring it.
Cost: roughly one to two percentage points above A pricing, a lender fee around one percent, terms of one or two years, and twenty percent down minimum. Full detail on B lender mortgages.
Tier three: mortgage investment corporations
Pooled funds where investors lend collectively, sitting between institutional and truly private lending. More expensive again, more flexible again, and generally short-term.
Used for files that need speed, unusual properties, or situations where the borrower needs twelve months to resolve something specific.
Tier four: private lenders
Individuals or small groups lending their own money, primarily against the property rather than the borrower. Credit and income matter far less; equity matters enormously.
Cost: substantially higher rates, combined lender and broker fees commonly two to four percent, one-year terms, frequently interest-only. It is expensive and appropriate only as a short bridge for a specific problem. See private mortgages.
The rule that matters: go no lower than you must
Each tier costs meaningfully more than the one above. The single most expensive mistake is landing in tier two or three when tier one would have said yes.
It happens constantly, because someone is declined at their own bank and concludes they are a bad credit risk. Frequently the truth is that one lender's income rules did not fit their pay structure, and three others would have approved them at normal pricing. A decline is a diagnosis rather than a verdict, and the reason determines the tier you actually need. See why lenders decline.
Before accepting alternative lending, the question worth asking is: has this file been to lenders whose rules fit it, or only to the one that declined it?
Using tier two properly
When it genuinely is the right tier, structure it as a bridge rather than a destination.
Take a one or two year term, not a five year one. Use that period to fix whatever caused the placement: build two clean trade lines, accumulate two years of returns showing sufficient income, or let a credit event age past twenty-four months. Then move to an A lender at renewal, when there is no penalty.
Agree that plan in writing at the outset, with a specific list of what has to change and by when. Alternative lending done this way is a sensible two-year cost that gets people into a house years earlier. Done without a plan it quietly becomes permanent, and that is where it gets expensive.
Questions to ask before signing anything below tier one
What is the total cost, including every fee? What is the term, and what happens at renewal? Is there a renewal fee? What is the penalty to break early, and is it different from a standard mortgage? What specifically do I need to change to qualify for an A lender next time?
A broker who cannot answer the last question is not giving you a plan, only a product.
