Moving a mortgage to a new lender means the old charge has to be discharged from title and a new one registered in its place, a step handled through a lawyer or notary at the provincial land registry or land titles office. Even on the simplest standard-charge switch, this is a real legal transaction with its own fees, separate from anything the lender itself charges — the exact process and cost vary by province and by which land registration system applies, but the underlying step is the same everywhere: out with the old registration, in with the new one.
In this context, the covenant refers to who is legally obligated to repay the mortgage — the borrower or borrowers named on the charge. A covenant change means adding a name (a spouse, a co-signer) or removing one (following a separation, a death, or simply taking someone off title who no longer needs to be there). This is a different kind of change from anything covered in the switch-versus-refinance discussion in Module 03, because the balance and amortization can stay perfectly unchanged and the transaction can still be far more involved than a straight switch.
Adding or removing a borrower changes the risk profile the lender is actually underwriting, even when the dollar amount on the mortgage doesn't move. A lender extending credit to two incomes is assessing a materially different file from one extending the same balance to a single income, and most lenders will not simply amend the existing registration to reflect a new covenant — they treat it, at minimum, as a full requalification of whoever remains or is being added, and in many cases as a transaction that has to proceed as a refinance regardless of whether any new money changes hands.
This is worth explaining to a client plainly and early: “we're not increasing what you owe” is not the same question as “are we changing who's on the hook for it,” and a client who assumes the first automatically simplifies the second is likely to be surprised by the actual timeline and process.
A handful of life events show up repeatedly around the transfer and renewal moment, and each one is a natural point for a broker to ask directly whether a covenant change is coming, rather than waiting to be told.
Any anticipated covenant change deserves early involvement from a lawyer or notary, since removing a name from title can carry provincial land transfer tax implications that vary significantly depending on the province and the relationship between the parties — the details are outside the scope of this course and genuinely require a legal or tax professional's specific advice, but a broker who raises the possibility early, rather than discovering it once the file is already underway, gives the client time to get that advice before it becomes a closing-week problem.
A couple separating wants one partner to take over their existing mortgage alone at the upcoming renewal, with the balance and amortization staying exactly the same. Is this a straightforward switch?
The balance and amortization staying flat only satisfies the definition of a straight switch on those two dimensions — removing a borrower is a separate change to who the lender is actually extending credit to, and that's what most lenders treat as requiring more than a routine switch, regardless of how strong the remaining borrower's income turns out to be. Whether the remaining partner ultimately qualifies is a real and separate question, but it doesn't change what kind of transaction this is to begin with.
