Lenders & Fees

A-Lender

Last updated: October 2026

What is A-Lender in Canadian mortgages?

Major banks (RBC, TD, BMO, Scotia, CIBC) and monolines (MCAP, First National, RMG). Best rates but strictest qualification requirements.

Why A-Lender matters

A-lenders offer the lowest rates, so most clients should be tried here first. They also have the strictest rules on credit, income documentation and the stress test, so a file that does not fit usually needs another channel.

What is the A-Lender limit for Canadian mortgages?

680+ credit, 39% GDS, 44% TDS

A-Lender example

Worked example

A salaried borrower with a 720 credit score, two years in the job and ratios under 39% GDS and 44% TDS is a typical A-lender file.

How brokers use A-Lender

  • Check credit, income documentation and ratios against A-lender limits before submitting, since a decline leaves a credit inquiry.
  • Monoline lenders work only through brokers, which can mean better rates and more flexibility than the big banks.
  • Self-employed and newer-to-Canada borrowers often fit better with an alternative lender even when their income is strong.
  • When a file fails at an A-lender, note the reason. It shows what to fix or which lender type to try next.
