# Are Fixed and Variable Mortgage Interest Rates Going Up Tomorrow in Ontario: Your Ultimate 2025 Guide
If you’re wondering whether mortgage interest rates are climbing tomorrow in Ontario, you’re not alone in this concern. As an FSRA licensed mortgage broker (M25001564) serving the Halton region and GTA, I field this exact question from clients almost daily. The reality is that rate movements aren’t predictable on a day-to-day basis, but understanding the factors driving these changes can help you make smarter mortgage decisions.
What makes 2026 particularly challenging is the combination of persistent inflation pressures, Bank of Canada policy uncertainty, and a housing market that’s showing signs of both cooling and resilience depending on your local area. Having access to over 50 lenders gives me a unique perspective on how different institutions are positioning themselves for rate changes.

Understanding Daily Mortgage Interest Rate Fluctuations in Ontario
Here’s what most people don’t realize about mortgage rate movements: they don’t follow a predictable daily schedule. Fixed mortgage rates are influenced by bond market activity, while variable mortgage rates track the Bank of Canada’s overnight rate, which changes only on scheduled announcement dates.
What we’re seeing with our clients in Halton, Ontario is anxiety about timing their mortgage applications or renewals. The truth is that trying to time the market perfectly often costs more than simply securing a competitive rate when you need it.
As of writing this article, the Bank of Canada maintains its policy rate at 3.25%, but this can shift during their eight scheduled announcement dates throughout the year. Fixed rates, however, move independently based on government bond yields and lender funding costs.
What Drives Fixed Mortgage Rate Changes
Fixed mortgage rates in Ontario don’t change overnight randomly. They’re primarily influenced by the Government of Canada 5-year bond yield, which fluctuates based on economic conditions, inflation expectations, and global market sentiment.
In my experience working with first-time buyers and renewal clients, I’ve noticed that lenders typically adjust their posted rates weekly or bi-weekly, usually on Mondays or Wednesdays. However, the actual rates available to qualified borrowers – what we call “special offers” – can change more frequently based on competition and funding needs.
Key Takeaway
Fixed mortgage rates typically change weekly, not daily, and are driven by bond market movements rather than Bank of Canada announcements.
Variable Mortgage Rates and Bank of Canada Decisions
Variable mortgage rates are more predictable in their timing. They only change when the Bank of Canada adjusts its overnight rate, which happens on predetermined dates throughout the year. The next scheduled announcement is typically six to eight weeks away from any given point.
What sets us apart is our ability to monitor multiple lenders’ variable rate offerings. While all variable rates move in the same direction following a Bank of Canada change, the spreads between lenders can vary significantly. Some credit unions in our network offer more competitive variable rates than the big banks.
For clients considering variable rates in 2026, I always explain that your payment structure matters as much as the rate itself. Some variable mortgages maintain fixed payments while others adjust payments with each rate change.
Current Rate Environment Analysis for 2025
What makes 2026 different is the combination of economic factors we’re navigating. Inflation remains above the Bank of Canada’s 2% target, employment levels are strong but showing signs of cooling, and housing affordability continues to challenge many Ontario families.
The reality is that both fixed and variable mortgage rates remain elevated compared to the ultra-low environment we experienced from 2020-2022. However, we’re seeing some stabilization in the 4.5% to 5.5% range for qualified borrowers with strong credit profiles.
One thing I always tell clients is that rate predictions beyond the next Bank of Canada meeting are essentially educated guesses. The CMHC and other housing agencies provide forecasts, but actual rate movements depend on factors that can change rapidly.
Strategies for Rate-Sensitive Borrowers
If you’re concerned about rate increases affecting your mortgage plans, here are practical strategies I recommend to clients in Milton, Oakville, and Burlington:
- Lock in your rate for 90-120 days when you find a competitive offer
- Consider a rate hold while you shop for properties
- Explore hybrid products that combine fixed and variable portions
- Ensure you qualify under current stress test requirements
- Review your debt service ratios to maximize your options
For self-employed clients, which represent a significant portion of my practice, I often recommend securing pre-approval early in the process. Alternative lenders in our network can provide more flexibility on income verification, but rates may be slightly higher.
Our mortgage combo calculator helps clients understand how different rate scenarios would affect their payments and total interest costs over time.
Regional Market Considerations
The impact of rate changes varies significantly across our service areas. A family purchasing in Milton might have different rate sensitivity than someone buying in Oakville, simply because of the price points and down payment requirements involved.
In Hamilton, where we’re seeing strong demand from Toronto buyers seeking affordability, even small rate increases can affect qualification amounts significantly. Meanwhile, in Mississauga’s condo market, the combination of rates and stress testing creates unique challenges for first-time buyers.
What I’ve learned from being a Milton resident since 2014 is that local market dynamics matter as much as interest rates. Areas with strong employment growth and transportation access tend to maintain value even during rate increase cycles.
Renewal Strategies in Rising Rate Environment
For homeowners facing mortgage renewals in 2025, the question isn’t whether rates might go up tomorrow, but how to position yourself for the best possible outcome when your current term expires.
Here’s the truth about renewals: your current lender’s renewal offer is rarely your best option. They’re counting on convenience and inertia. Having access to 50+ lenders means I can often find better rates or terms than what you’ll receive in your renewal letter.
Our comprehensive 2026 mortgage renewal guide covers strategies for different scenarios, including what to do if your home value has declined or your income has changed.
Renewal Tip
Start your renewal process 4-6 months before your maturity date. This gives you time to explore options without pressure and potentially secure better terms.
Alternative Lending Options When Rates Rise
When traditional mortgage rates increase, alternative lending becomes more relevant for certain borrowers. Credit unions, private lenders, and specialized mortgage investment corporations all play important roles in our lending ecosystem.
For clients with unique income situations or credit challenges, these alternatives can provide solutions when big banks tighten their criteria. The key is understanding the trade-offs between rate, terms, and qualification requirements.
Our self-employed mortgage guide explains how alternative lenders evaluate business income and what documentation you’ll need to secure competitive rates.

Rate Protection and Timing Strategies
Given the uncertainty around future rate movements, protecting yourself from increases while maintaining flexibility for decreases becomes crucial. Rate holds, convertible options, and hybrid products all serve different purposes in this environment.
For clients worried about rates going up tomorrow, I often recommend securing a rate hold on a competitive offer while continuing to monitor the market. Most lenders offer 90-120 day holds, giving you time to find the right property without rate risk.
The Financial Services Regulatory Authority of Ontario requires that we explain all costs and terms clearly, including any fees associated with rate protection products. Transparency in these discussions helps you make informed decisions.

Frequently Asked Questions
Do mortgage interest rates in Ontario change daily?
Fixed mortgage rates typically change weekly, not daily, and are influenced by government bond yields rather than daily market fluctuations. Variable rates only change when the Bank of Canada adjusts its policy rate on scheduled announcement dates. However, lender promotions and special offers can change more frequently based on funding needs and competition.
Should I lock in my rate if I think rates are going up?
Rate holds are valuable protection tools that typically last 90-120 days at no cost. If you’ve found a competitive rate and are actively house hunting, securing a hold protects you from increases while maintaining your qualification. However, remember that rates can also decrease, and you’ll be locked into your held rate regardless.
How much do mortgage rates typically increase at once?
Variable rates move in increments of 0.25% (25 basis points) following Bank of Canada announcements. Fixed rates can move more gradually, often changing by 0.10% to 0.30% based on bond market conditions. Large single-day movements are rare, but weekly changes of 0.15-0.25% can occur during volatile periods.
What’s the difference between posted rates and actual rates available?
Posted rates are the advertised rates lenders use for qualification purposes, but most qualified borrowers receive discounted rates. The spread between posted and available rates varies by lender and can range from 0.50% to 2.00%. This is where having access to multiple lenders becomes valuable for finding the best actual rates.
Are mortgage rates higher in smaller Ontario cities like Milton compared to Toronto?
Mortgage rates are generally consistent across Ontario for the same lender and product type. However, local credit unions might offer competitive rates in specific areas, and some lenders have different appetite for certain regions. Property type and value can influence available products, but location within Ontario typically doesn’t directly affect your rate.
