Her bank registered a mortgage for 125% of what her house is worth. She never noticed. In Ontario that is legal, and it bites at renewal, because a charge like that cannot be handed to a cheaper lender.
A Milton example. A couple buys for $800,000 with 20% down, a $640,000 mortgage. The bank registers a collateral charge for $1,000,000, 125% of the value, the most some lenders register. Nobody explains it at signing. Five years on, a broker finds a better renewal rate, and the new lender cannot take it over. The old charge is discharged, a new one registered, a lawyer paid, roughly $1,000 to $1,900 by one broker's estimate, and their line of credit at the same bank must be cleared first.
How it works. A standard charge secures the mortgage alone, for what you borrowed, and at renewal another lender can usually take it over for a small fee. A collateral charge can be registered for more than you owe and can stand behind other borrowing at the same bank. Some lenders, TD among them, register every mortgage this way.
Why it exists. The Financial Consumer Agency of Canada lists the upside: you can borrow more later on the same registration without paying to discharge and re-register, and you pay interest only on what you draw. It suits the borrower who wants a line of credit later. The cost lands on the one who leaves.
The fixes. Before you sign, ask in writing: standard or collateral, and for how much? If you have one, shop 120 days before renewal and ask the new lender what the switch costs and who pays it.
Save this before your renewal letter comes, and send it to the friend who signed whatever the bank sent.
