Every Canadian mortgage is secured by a charge (the term used in most common-law provinces; Quebec uses a hypothec under its own civil-law framework) registered against the property at the provincial land registry or land titles office. The charge is what actually gives the lender the right to force a sale if the borrower stops paying — it is the legal instrument, separate from the mortgage contract itself, and how it is drafted decides a great deal about what happens later.
There are two broad ways a lender registers that charge, and the choice is made by the lender, at origination, usually without much explanation to the borrower. Understanding both is essential to advising a client honestly about what a future switch will actually cost them.
A standard charge secures only the specific mortgage loan described in the document — the amount, the rate, and the term are written into the registration itself. Because the charge doesn't reach beyond that one loan, a new lender taking over the mortgage at renewal is stepping into a clearly bounded obligation. In practice this generally makes a standard-charge mortgage cheaper and simpler to move: some transfers can proceed as a straightforward discharge-and-reregister at modest legal cost, without the lender needing to treat it as a materially more complex transaction than a normal renewal.
A collateral charge is registered for an amount that can be well above what was actually advanced — commonly used by lenders offering readvanceable products that bundle a mortgage with a home equity line of credit, so the client can borrow more later against the same property without a brand-new registration. That flexibility for the client while they stay with the same lender is exactly what makes it inflexible when they want to leave.
Because a collateral charge secures more than just the stated mortgage — potentially other products or future advances under the same lender relationship — a new lender generally will not simply step into it. The client's existing lender has to fully discharge the old charge before a new one can be registered, which means real legal fees, sometimes a new appraisal, and a transaction that looks and costs more like a fresh mortgage than a routine switch.
Most clients never choose between a standard and collateral charge consciously — the lender's product simply comes registered one way or the other, and the difference rarely comes up unless a broker raises it. A client taking a readvanceable mortgage-plus-HELOC product from a major bank is very likely getting a collateral charge, in exchange for the convenience of accessing more equity later without a new application. A client with a conventional single-purpose mortgage from a monoline lender is more likely holding a standard charge.
This is precisely why the topic belongs at origination, not just at renewal: a broker who explains the trade-off honestly when the mortgage is first placed — flexibility to borrow more later, against flexibility to leave more cheaply later — gives the client an informed choice instead of a surprise three or five years down the road.
By the time a client is thinking about a switch, they usually don't know which type of charge they have, and their mortgage statement doesn't always spell it out in plain language. The most reliable ways to confirm it are the original charge or mortgage document itself (available from the lawyer or notary who handled the closing, or from the land registry directly), a direct question to the current lender or its solicitor, or in some cases the mortgage commitment letter from origination, which will usually name the product type.
A client with a collateral-charge mortgage wants to switch lenders at their upcoming renewal to get a materially better rate. What should the broker expect, compared to a client with a standard charge doing the same thing?
A collateral charge's higher registered amount exists to secure potential future borrowing, not to make anything cheaper — it's exactly what a new lender won't accept without a full discharge and fresh registration, which brings real legal cost and complexity a standard-charge switch usually avoids. It isn't impossible to switch out of a collateral charge, just materially more expensive and involved, which is the honest expectation to set before the client compares rate quotes.
