Buying out a co-owner reaches 95% LTV because insurers treat it as a purchase of the departing owner's interest, not as a refinance — a refinance is capped at 80% by the Bank Act. Sagen publishes this as "Equity Buy-Out" and Canada Guaranty as the buyout of a co-borrower's interest; both require that all parties are currently on title, and Canada Guaranty refers every such application for manual review. CMHC does not publish an equivalent policy. Insured lending is unavailable at or above $1,500,000 of property value. Because it is a purchase, the insurance premium applies to the whole new mortgage rather than only to the new money. Speak with a mortgage broker for your specific situation.
