Credit and lender tiers

Credit requirements, read the way a lender reads them.

A score is a summary, not the decision. Lenders read the file underneath it — how long it is, how much of your available credit you use, and whether anything went wrong recently — and that reading decides which tier of lender you belong to.

Executive summary

What a lender actually reads

Definition

Credit file, not credit score
The score is a single number produced from the file. Underwriters look at the file itself: how many accounts, how long each has reported, the balance-to-limit ratio on each, the pattern and recency of late payments, how many recent enquiries there are, and whether any account went to collection, settlement, proposal or bankruptcy.

Under OSFI's Guideline B-20, federally regulated lenders are expected to assess a borrower's background and demonstrated willingness to service debt using reliable, independently sourced information. A bureau report is that evidence. It is read alongside income and equity, not in isolation — strong equity can offset a mediocre file, and a thin file undermines an otherwise strong application.

Primary sources

Regulation sets the standard of assessment. Insurer guidance sets minimums on default-insured mortgages. Individual lender policy sits on top of both and is not published.

Minimums, policy and practice are three different things

Most confusion about "the credit score you need" comes from collapsing three separate layers into one number. They are not the same, and only one of them is published.

The three layers that decide whether a credit profile qualifies
LayerWho sets itPublished?Effect on your file
RegulationOSFI, via Guideline B-20YesRequires assessment of willingness and capacity to repay; sets no score number
Insurer guidanceDefault insurers on insured mortgagesYes, in insurer documentationSets a minimum score and credit-history expectation for insurability
Lender policyEach lenderNoSets the tier, the rate, and what exceptions an underwriter may grant
The three layers that decide whether a credit profile qualifies

The practical consequence: anyone quoting one exact score that "every Canadian lender" requires is describing a convention, not a rule. Ask instead which tier your file lands in and what it costs.

Utilization is the fastest lever you control

Scoring models weigh the reported balance against the limit on each revolving account. The balance that matters is the one the creditor reports on its statement date — not the balance after you pay the bill. Paying in full every month can still report high utilization if the statement cuts before your payment lands.

How we calculated this

The example below applies standard debt-service arithmetic: revolving debt is counted in the total debt-service ratio using the greater of a lender's minimum monthly payment convention or the actual required payment. It uses a 44% TDS limit and a 6.39% qualifying rate over 25 years, and is illustrative rather than lender-specific.

Full methodology and source review policy

Worked example: the cost of a carried balance

Worked example

$14,000 on a $15,000 line of credit, before and after paydown

Limit
$15,000
Balance
$14,000
Utilization
93%
Counted payment
$420/mo

At 93% utilization the file is scored as heavily extended even with a perfect payment history. A lender counting 3% of the balance as the monthly obligation adds $420 per month to the total debt-service calculation.

At a 44% TDS ceiling, $420 of monthly obligation consumes $420 of housing capacity. At a 6.39% qualifying rate over 25 years, that is roughly $63,000 of mortgage — before any score effect on pricing.

Paying the balance down to $4,500 does two things at once: the counted obligation drops to about $135 per month, restoring roughly $43,000 of capacity, and utilization falls to 30%, which typically improves the score within one reporting cycle. Same income, same deposit, materially different pre-approval.

Illustrative only. Figures are examples, not an offer, quote, or approval.

Collections, consumer proposals and bankruptcy

Derogatory items are assessed on three axes: how recent, how large, and whether the matter is resolved. A $180 telecom collection from four years ago, paid, is a conversation. An unpaid $9,000 collection reported last quarter is a decline at most A-lenders until it is settled.

  • Open collections and judgments. Usually must be paid and evidenced before funding. Expect the lender to ask for a paid-in-full letter, not a receipt.
  • Consumer proposal. Lenders generally look for the proposal to be fully discharged and for re-established credit afterwards — typically two active tradelines reporting satisfactorily for a period the lender specifies. Insured financing after a proposal is possible but policy-dependent.
  • Bankruptcy. Same logic, longer clock, and lenders will ask for the discharge certificate and the statement of affairs.
  • Tax arrears. Outstanding balances with CRA can rank ahead of a mortgage; they are usually a funding condition rather than a scoring issue.

None of these are permanent. What lenders price is the re-established pattern that follows them.

Which lender tier your file points to

Lender tiers by credit profile. Illustrative of common Canadian market structure; individual lenders differ.
TierTypical profileWhat to expect
Prime (banks, monolines)Strong score, two-plus seasoned tradelines, no recent derogatory items, verifiable incomeBest available pricing, full documentation, insured or uninsured
Near-prime / alternativeBruised recent history, thin file, or income that prime documentation cannot captureHigher rate, larger down payment, lender fee, shorter term with an exit plan
PrivateRecent unresolved credit events, urgent timing, or property-driven dealsEquity-driven, short term, fees; used as a bridge, not a destination
