Todd and Clinton's Merry Debtmas conversation continues, this time discussing the ins and outs of mortgage refinancing and renewals, highlighting recent changes to Canadian mortgage rules. 

Key points include the introduction of high-ratio insured mortgages with a 30-year amortization and an increased limit to $1.5 million. They also cover the return of high-ratio insured refinances up to 90% of the home's value, specifically for adding secondary units. Clinton emphasizes the importance of timing refinances during renewals and the complexities involved, such as zoning and financial incentives.
