What this list shows
Credit unions are member-owned financial co-operatives. Most credit unions in Ontario are regulated by the province, through the Financial Services Regulatory Authority of Ontario; a few operate as federal credit unions. Borrowing usually requires membership, on terms each credit union sets.
For an uninsured mortgage, a provincially regulated credit union is not bound by the federal regulator’s B-20 guideline, so its qualification rules can differ from a bank’s. An insured mortgage follows the federal mortgage insurance rules at any lender.
This list gathers the records published by the credit unions in this directory and shows one record per credit union. It mixes terms, insured and conventional rates, and open and closed products, so read the conditions beside each rate before comparing two numbers.
Records are ordered by the smallest displayed rate so the list is easy to scan. That order is not a ranking of which mortgage suits you, and it says nothing about which lender would approve an application.
Published rates only, in each lender's own wording. This is not a recommendation or an approval. Rates can change after the date shown; open the lender's source and ask for a current quote before acting.
