What refinancing actually is
A refinance replaces your existing mortgage with a new one, usually for a larger amount, and gives you the difference in cash. Your current mortgage is paid out and discharged, a new charge is registered on your home, and you start a fresh term. It is worth separating from a renewal, which is simply a new term on the same balance at maturity, and from a second mortgage, which sits behind your existing one rather than replacing it.
People refinance in BC to consolidate other borrowing into one secured payment, to fund a renovation, to free up a down payment for a second property, to fund a business or an education, or to restructure after a change in the household. All of them turn on the same two questions: how much equity is available, and what the timing costs.
How much you can borrow: the 80% line
The headline number in Canadian refinancing is 80% of your home's value. FCAC states it directly: you may usually borrow up to 80% of your home's value when borrowing against home equity (FCAC). That ceiling counts everything secured against the property, not only the new first mortgage.
It sits at 80% because of how default insurance works. OSFI's Guideline B-20 notes that residential mortgages underwritten to purchase, renovate or improve a property must be insured where loan-to-value exceeds 80 percent, and ordinary equity-takeout refinances are not eligible for that insurance.
Value is established by an appraisal, not by your BC Assessment notice — assessment is a mass-valuation figure produced for property tax purposes at a fixed point in the year, while a lender wants a current opinion of market value for your specific home. In the Okanagan, where a view, a lot line or a suite can separate two houses on the same street, that difference is often worth real money.
| Route | How it works | Typical ceiling | Best suited to |
|---|---|---|---|
| Refinance | Existing mortgage is paid out and replaced with a new, larger one on a new term. | Up to 80% of value. | A defined lump sum: consolidation, a renovation budget, a down payment. |
| HELOC | Revolving credit secured on your home; draw and repay as you go. | Up to 65% of value on the revolving portion; up to 80% combined with an amortizing portion. | Staged or uncertain spending, or a standing reserve. |
| Second mortgage | A separate loan registered behind your first mortgage, which stays as it is. | Set by the lender, within overall equity. | Keeping a first mortgage untouched mid-term. |
| Blend-and-extend | Your lender blends your current rate with a new one and extends the term; some allow new money in the blend. | Lender policy. | Staying put, with modest additional funds. |
Refinancing mid-term: how the prepayment charge is built
Refinancing before your term is up means ending the term early, and closed mortgages carry a prepayment charge for that. Knowing how it is calculated turns it into a line item you can plan around. FCAC sets out both methods (FCAC).
Three months' interest
An amount equal to three months' interest on the balance you still owe. It is the usual method on variable-rate mortgages, and it also applies on fixed mortgages where the interest rate differential comes out lower.
The interest rate differential
The IRD applies where the rate on your mortgage is higher than the current comparable rate and you signed less than five years ago. The lender works out the interest still payable over the remainder of your term at your rate, does the same using a comparison rate, and charges the difference.
Three inputs drive its size: the rate used for your side (your contract rate, or the posted rate at the time you signed, depending on your contract wording); the comparison rate (the lender's current rate for a term closest to your remaining time, sometimes with your original discount subtracted); and the time remaining, since fewer months left means fewer months of difference to add up. On a closed fixed mortgage the charge is generally the higher of the two calculations.
Get the exact number before you decide anything
Every one of those inputs lives in your mortgage contract, and the wording varies between lenders. Your lender will calculate your figure on request, usually same-day, quoted as good to a stated date, and I ask for it at the very start. Two items belong in the same request: any cash-back to be repaid, and your remaining prepayment privileges — using an annual lump-sum privilege first reduces the balance the charge is calculated on.
Consolidating other borrowing
This is the most common refinance I arrange. Unsecured borrowing — credit cards, lines of credit, vehicle loans, instalment plans — is priced for being unsecured and amortizes far faster than a mortgage. Rolling it into a mortgage moves it to secured pricing over a longer schedule, lowering the total of your monthly obligations, often substantially.
Two things make a consolidation work especially well. The first is arithmetic: a longer schedule spreads interest over more years, so the monthly relief is real and the lifetime cost deserves a look too. Many clients deliberately keep paying the old total into the new mortgage as prepayments, capturing the lower cost of borrowing while keeping the timeline short. The second is a qualifying benefit — because the consolidated payments come off your monthly obligations, your debt service ratios improve, which often opens up lenders and terms that were not available beforehand.
Renovation financing, including suites
For renovations there are three routes, and choosing between them is mostly a question of how the spending will happen: a refinance suits a defined budget, a HELOC suits staged work where the total moves, and a purchase-plus-improvements mortgage suits work planned at the time you buy.
There is also a federal program worth knowing if you are adding a suite, which matters in BC where secondary and carriage suites are widely permitted. Since January 2025, CMHC has insured refinances specifically to build a self-contained secondary suite, at up to 90% loan-to-value on owner-occupied properties of up to four units, with a maximum property lending value of $2 million and amortization up to 30 years. The funds must go to construction — equity take-out is not permitted — the suite must comply with local bylaws, and it cannot be rented for periods under 90 consecutive days (CMHC). For a Kelowna homeowner with the lot and the zoning for it, that is the one route above the usual 80% line.
What a refinance costs to arrange
- Appraisal. Nearly always required, since the transaction is priced off current value. Some lenders cover it.
- Legal fees and registration. The old charge is discharged and a new one registered at the Land Title Office, which is lawyer or notary work. Some lenders offer a legal package or rebate.
- Discharge fee. Charged by the outgoing lender for removing their charge from title.
- Prepayment charge. Only if you refinance before maturity, calculated as above.
- Title insurance. Commonly required, and usually a modest part of the closing package.
One cost that does not apply: BC property transfer tax is triggered by acquiring a registered interest in property, and a refinance registers a charge without changing who is on title, so it is not a taxable transaction (Government of BC). On conventional mortgages, there is no cost to you for my work.
Choosing the timing: now, or at renewal
Both are good options, and the choice comes down to how the money will be used and how much term you have left.
Refinancing now works well when the funds do something time-sensitive: consolidating higher-cost borrowing that is compounding today, funding a renovation with a contractor booked, or freeing a down payment for a purchase with a date on it. Every month of waiting carries a cost of its own, and the arithmetic usually favours acting — as it does when you are close enough to maturity that a charge calculated on the remaining months is small.
Waiting for renewal works well when the need is flexible and your maturity date is near, because at maturity the term ends on its own and the prepayment question disappears entirely. Within a few months of maturity we can often line the refinance up to complete exactly then, capturing both the funds you want and a clean start on a new term.
The way I settle it is simple: get the exact prepayment figure from your lender, price the refinance across my lender panel both ways, and put the two timelines beside each other. That answers the question in about a week, with real numbers rather than assumptions.
What I need to price a BC refinance
Your current mortgage statement, your lender's quoted prepayment figure if a mid-term move is on the table, the balances you would like to fold in, income documentation and the property address. From there I take the file to more than 50 lenders — banks, credit unions, monoline and specialty lenders — and come back with what is achievable, what each route costs to arrange, and a recommendation with the reasoning behind it.
