## Who this is for
Salaried borrowers approaching a mortgage renewal who have received a posted-rate offer from their current lender and want to determine whether negotiating in place or switching to a competing lender produces the better financial outcome.

## Summary
At renewal, your current lender's opening offer is almost never their best offer — and a competing lender's best offer is almost never free to access. The decision framework turns on three variables: the rate spread between staying and switching, the all-in cost of switching (legal, discharge, appraisal, and time), and whether your file qualifies for a straight switch under OSFI's December 2024 guidance. For most salaried borrowers with a clean file and an LTV below 80%, the spread needs to exceed roughly 15–20 basis points on a $500k balance to justify a full lender switch; below that threshold, a negotiated match from your current lender is the dominant strategy.

## Worked example
A salaried borrower in Ontario has a $480,000 balance renewing in June 2026. Their current lender's posted renewal offer is 5.35% on a 5-year fixed. A competing monoline is offering 4.95% on the same term. The borrower's LTV is 68% (uninsured), and the property is a standard detached home with a conventional charge — eligible for a straight switch.

- Current lender posted offer: 5.35% 5-year fixed
- Competing monoline offer: 4.95% 5-year fixed
- Interest saving at 4.95% vs 5.35% over 5 years: ~$9,600 on $480k balance
- Estimated all-in switch cost (legal + discharge + appraisal): $1,200–$2,000 if not covered by receiving lender
- Negotiated counter-offer from current lender: 5.05–5.10% (typical response to a competing term sheet)

## Framework
### Step 1 — Establish your true rate floor before any negotiation
Before contacting your current lender, obtain at least two written rate commitments from competing lenders or through a broker with access to monoline pricing. Posted renewal rates from incumbent lenders are typically 30–60 bps above what the same lender will approve when presented with a competing offer. In the 2025–2026 rate environment (5-year fixed broadly in the 4.85–5.35% range depending on insured vs uninsured status and term), the spread between a lender's unsolicited renewal letter and their negotiated floor is often 25–40 bps. You cannot negotiate credibly without a documented alternative — a verbal quote is insufficient leverage.

### Step 2 — Determine whether your file qualifies for a straight switch
Under OSFI's December 2024 guidance, a straight switch — transferring your mortgage to a new federally regulated lender at renewal without increasing the loan amount — does not require the receiving lender to re-qualify you under the Minimum Qualifying Rate stress test. This is a material advantage: a borrower whose income or debt ratios have shifted since origination can still access competitive pricing at a new lender without a full underwrite. Eligibility conditions: the balance cannot increase, the amortization cannot extend, and the property must support the existing charge type. Collateral charge mortgages (common at TD, National Bank, and Scotiabank) complicate transfers — a collateral charge cannot be transferred directly and requires a full discharge and re-registration, adding $800–$1,500 in legal costs.

### Step 3 — Calculate the break-even spread
The decision to switch is financially justified when: **(Rate differential × Balance × Remaining term in years) > All-in switching costs**. On a $480k balance, 1 bps of rate difference equals approximately $240/year in interest. A 40 bps spread generates ~$9,600 over five years. If the receiving lender covers legal and appraisal costs (common practice among monolines and credit unions competing for renewal business), the net switching cost can be near zero, making even a 15–20 bps spread worth capturing. If costs are not covered, a $1,500 switching bill requires a spread of at least 6–7 bps just to break even — meaning anything above ~10 bps net is a clear switch signal. Run this arithmetic with your specific balance before deciding.

### Step 4 — Execute the negotiation with your current lender
Present the competing term sheet directly to your current lender's retention desk — not the branch, not the renewal letter phone number. Most major banks have a dedicated mortgage retention team with authority to match or beat competing offers. The script is straightforward: state the competing rate, the lender name, and the term, and ask whether they can match it. Do not volunteer that you prefer to stay. Retention desks have discretion to move 15–30 bps below their posted renewal rate in most cases. If the lender matches within 5 bps of the competing offer, staying is usually the rational choice given zero switching friction. If they offer less than a 10 bps improvement on their posted rate, the competing lender's offer is likely the better path.

### Step 5 — Factor in non-rate switching costs and benefits
Rate is the dominant variable but not the only one. Evaluate: **(a) Prepayment privileges** — some monolines offer 20/20 (20% lump sum + 20% payment increase annually) vs a big bank's 10/10 or 15/15. On a $480k balance, the difference in prepayment room is meaningful if you plan to make lump-sum payments. **(b) Portability terms** — if you may sell and buy within the term, confirm the receiving lender's portability window (typically 60–120 days) and blending methodology. **(c) IRD penalty structure** — fixed-rate mortgages at major banks use a posted-rate IRD calculation that can generate penalties 3–5× larger than a monoline's bond-yield IRD. If there is any chance you break the mortgage early, the penalty structure matters as much as the rate.

### When staying is the dominant strategy regardless of rate
Three situations make staying with your current lender the correct answer even if the competing rate is modestly better: **(1) Collateral charge with no equity to spare** — if your lender holds a collateral charge and you have less than 20% equity, switching requires a full discharge plus a new insured mortgage, triggering CMHC premium on the full balance. **(2) Income or credit deterioration since origination** — even with the straight-switch stress-test exemption, receiving lenders still conduct a basic credit and income review. A borrower with a recent job change, elevated TDS, or a credit event may find that the straight-switch exemption does not fully protect them from a decline. **(3) Renewal within 90 days of a planned refinance or sale** — the friction of switching lenders only to break the mortgage shortly after rarely pencils out.

## Key considerations
- The 180-day early renewal window at your current lender is a negotiating asset: locking in a rate 4–6 months early with your incumbent costs nothing and gives you a floor while you shop competing offers. If the market moves in your favour before maturity, you can still switch.
- Insured mortgages (LTV above 80% at origination) carry a structural rate advantage at renewal — insured straight switches attract the lowest monoline pricing because the lender bears no default risk. Uninsured borrowers switching lenders face a 10–20 bps rate premium at most monolines relative to insured equivalents.
- Broker-sourced competing offers are generally more competitive than direct-to-lender offers because brokers access volume-discount pricing tiers unavailable at branch. A broker's competing term sheet is also more credible leverage with your current lender's retention desk than a rate you found on a comparison website.
- The December 2024 OSFI straight-switch guidance applies to federally regulated financial institutions. Credit unions are provincially regulated and their renewal transfer policies vary by province — confirm with the receiving credit union whether they apply equivalent underwriting flexibility.
- If your renewal falls in the first half of 2026, the BoC overnight rate at approximately 2.75% has already been cut materially from its 2023 peak. Variable-rate products are now priced at roughly 5.25–5.75% (prime minus spread), which is competitive with 5-year fixed. The fixed-vs-variable decision at renewal deserves a separate analysis — do not default to fixed simply because it was the right call in 2022–2023.

## Common mistakes
- Signing the renewal letter without negotiating — the posted renewal rate is a starting position, not a final offer. Borrowers who sign without engaging the retention desk typically leave 20–40 bps on the table, equivalent to $4,800–$9,600 in excess interest on a $480k balance over five years.
- Treating the competing offer as the end goal rather than leverage — the optimal outcome for most borrowers is a negotiated match from their current lender at near-zero switching cost, not necessarily the switch itself. Fixating on switching can cause borrowers to incur $1,500+ in costs for a 5 bps improvement.
- Ignoring the charge type on their existing mortgage — borrowers with collateral charges who assume they can do a straight switch discover at the last moment that a full discharge is required, adding cost and potentially delaying closing past their maturity date.
- Contacting the branch instead of the retention desk — branch staff typically have no authority to deviate from posted renewal rates and will quote the same rate as the renewal letter. The retention desk is a separate function with a different mandate and pricing authority.
- Failing to account for prepayment privilege differences when comparing rates — a monoline offering 4.95% with 20/20 prepayment privileges is materially better than a bank offering 5.00% with 10/10, for a borrower who makes annual lump-sum payments.
- Letting the renewal lapse to maturity without a signed commitment — an unsigned mortgage at maturity converts to an open mortgage at the lender's posted open rate, which in the current environment runs 6.5–7.5%. Even a suboptimal signed renewal is better than an open-rate default.

## Action steps
1. Pull your current mortgage statement and confirm three things: your maturity date, your outstanding balance, and whether your mortgage is registered as a standard charge or collateral charge. This determines your switching options and costs before you make a single call.
2. At 120–150 days before maturity, engage a mortgage broker to obtain written competing rate commitments from at least two monolines or alternative lenders. Request that the broker confirm whether each lender covers legal and appraisal costs for switches.
3. Contact your current lender's mortgage retention desk — not the branch — and present the competing term sheet. State the rate, term, and lender name. Ask specifically: 'Can you match or beat this offer?' Document the response in writing (email confirmation).
4. Run the break-even calculation: multiply your balance by the rate differential and the term in years. Compare that figure to your all-in switching cost. If the net saving exceeds $2,000 after costs, the switch is likely worth executing.
5. If switching, confirm the receiving lender's portability terms, prepayment privileges, and IRD penalty methodology before signing. A 10 bps rate advantage can be erased by a restrictive penalty structure if you sell or refinance mid-term.
6. Sign a commitment — either with your current lender or the new one — no later than 30 days before maturity. Do not allow the file to drift to an open-rate default while you continue negotiating.
