Default explained
Default occurs when a borrower does not fulfill their mortgage obligations as set out in the agreement. The most common trigger is missed payments, but default can also result from failing to pay property tax, letting home insurance lapse, or otherwise breaching the mortgage terms.
Once in default, the borrower usually receives notice and a chance to bring the loan current. If they cannot, the lender may pursue legal remedies to recover what is owed, including foreclosure or power of sale depending on the province.
