Treadstone's Canadian Mortgage Underwriting Course introduces insured, insurable and uninsurable in a single module: what pushes a file into each bucket, the December 2024 changes to the price cap and amortization, and the minimum down payment math. That is the right amount of depth for a broker who needs to recognize the category on sight and explain it to a client in two minutes.
This course assumes that module, or equivalent knowledge, and goes considerably further. If the words insured, insurable and uninsurable are new to you, start with that module first — the link is in this course's final module — then come back here for the mechanics.
Five things a broker needs once they are past the definitions: the actual premium tables and who is responsible for paying each premium; the full detail of what changed on 15 December 2024 and why so much older training material is now wrong; how amortization limits differ by category and by borrower type, not just a single number; how a paid premium ports, in whole or in part, to a new property; and how the category feeds directly into rate tiering before term, product or anything else on the rate sheet is considered.
Every premium percentage, threshold and date in this course is drawn from a primary source — CMHC's own published pages and notices, OSFI's guidance, or the two private mortgage insurers, Sagen and Canada Guaranty, describing their own programs. Private-lender or bank-specific overlays exist on top of these baseline figures and change without notice; where this course cannot verify a specific number against a primary source, it says so rather than guessing.
This course is best taken:
This course builds directly on the category definitions taught in the flagship course's insurance module, so it is designed as a follow-on, not a replacement or a prerequisite-free starting point. It matters for every deal, not only private uninsurable ones, because the category sets pricing even on straightforward insured purchases. And insurance category interacts directly with debt servicing — insured files are held to specific GDS/TDS ceilings, covered later in this course — so treating the two as unrelated would miss a central connection.
