The short version
- A standard charge mortgage secures only the mortgage itself. A collateral charge can secure the mortgage plus other borrowing, like a line of credit, under one registration.
- Switching lenders on a standard charge at renewal is typically straightforward. A collateral charge generally has to be discharged before it can move to a new lender, per the Financial Consumer Agency of Canada.
- This isn't a reason to avoid a collateral charge — readvanceable products built on one, like RateShield Advance, trade easy switching for flexibility to restructure without a full refinance.
- The only way to know which one you have is to ask, or check your mortgage documents. It usually isn't printed anywhere obvious.
What actually gets registered against your home
Every mortgage is registered against your property's title, but not every registration says the same thing. The Financial Consumer Agency of Canada draws a clear line between the two: "A standard charge only secures the mortgage. It doesn't secure any other loans you may have with your lender, like a line of credit." A collateral charge is different — it can secure the mortgage and other borrowing with the same lender under one combined registration.
The two can carry identical terms, an identical balance and an identical payment. The difference is entirely in the paperwork behind them — which is exactly why most borrowers never think about it until they try to leave.
Why the difference only shows up when you try to switch
A standard charge, registered for the exact amount borrowed, can generally be assigned to a new lender at renewal without much friction — new lenders competing for the business typically absorb most of the switching cost themselves.
A collateral charge works differently, and the FCAC's own research into readvanceable mortgages and home equity lines of credit is direct about it: such a charge "can be more expensive to discharge than a conventional charge," and consumers "cannot easily switch the amortized mortgage portion of a readvanceable mortgage to another lender." To move it, the FCAC notes, a borrower needs to resolve every credit account tied to that mortgage under the collateral registration first — not just the mortgage balance.
This is a trade-off, not a warning against collateral charges
A collateral charge isn't a worse product — it's a different one, built for a different priority. The Financial Consumer Agency notes that with a collateral structure, "you avoid paying fees to discharge your mortgage and register a new one" every time you draw on the line of credit portion; you only pay interest on what you actually borrow. That flexibility is the entire point of a readvanceable mortgage.
It's the same trade-off behind a product like our own RateShield Advance: a readvanceable structure that lets a household restructure mid-term without a full refinance, precisely because it's built on a collateral charge. The people it suits best are the ones who value that flexibility more than they value shopping lenders at renewal — not everyone, and that's fine.
How to find out which one you actually have
- It usually isn't obvious from your statement — ask your current lender directly whether your mortgage is registered as a standard charge or a collateral charge.
- Your original mortgage commitment or the land title registration itself will state it, though the wording varies by lender.
- If you have a line of credit or other borrowing tied to the same lender as your mortgage, a collateral charge is likely — that combined structure is exactly what a collateral registration is built to support.
Knowing the answer before renewal, not during it, is what turns this from a surprise into a decision. If a straight renewal with your existing lender is the plan, the charge type barely matters. If shopping lenders is on the table, it's the first thing worth confirming.
