Interest Rate Hikes Eroding Housing Affordability

Lisa Manwaring • July 10, 2018

After improving slightly late last year, housing affordability has now reached “crisis levels” in Vancouver and is posing a “tremendous challenge” in Toronto.

That’s the assessment from RBC’s latest Housing Trends and Affordability report, which says higher interest rates are the main reason for a deterioration in affordability right across the country.

“The winning streak for housing affordability in Canada ended,” the report reads, noting the aggregate affordability measure for Canada rose by 0.4 percentage points to 48.4% in Q1. “This rise entirely reversed the slight 0.3 percentage-point decline recorded in the previous quarter—the first decline in 10 quarters.”

Unsurprisingly, Toronto and Vancouver led the way as the country’s least affordable markets.

In Vancouver it takes 87.8% of household income to cover the costs of home ownership, the report said, while in Toronto that percentage is 74.2%. Compare that against the national average of 48.4%, or 43.7% in Montreal, 43% in Calgary and just 28% in Edmonton.

“[Affordability] is at crisis levels in Vancouver and poses a tremendous challenge for many Toronto-area buyers despite improving in the past two quarters,” the report noted.

Overall, higher interest rates were cited as the main factor for sending homeownership costs to a multi-decade high, while the situation was amplified in both Vancouver and Victoria due to a return to appreciating prices.

Although affordability in Toronto remains a concern, the report noted that it was one of only two markets, along with Winnipeg, to see a small improvement.

“The main reason was that home prices fell enough in both markets to counteract the effect of higher interest rates,” RBC noted. “In the case of the Toronto area, the mortgage stress test that came into effect in January added further downward pressure on property values—which were still adjusting to last year’s Fair Housing Plan implemented by the Ontario government.”

But that may not be the case for much longer, as the Toronto Real Estate Board’s latest datashows the average price of a home in the Greater Toronto Area climbed to a 13-month high in June—up 2 percent year-over-year to $807,871.

National Bank published similar findings to RBC recently in its Housing Affordability Monitor. It noted that the mortgage payment on a representative home as a percentage of median income rose by 1.2 points—the 11th straight month that this metric had increased.

Given the limited capacity for Vancouver and Toronto homebuyers to put more of their income towards housing than they already are, the National Bank report concluded that prices could start to decline should interest rates continue to increase.

“Since we don’t see how Vancouver and Toronto homebuyers could pay a higher share of their incomes for shelter, a downward adjustment of prices is conceivable,” the authors write. “If our scenario for interest rates out to the end of 2019 materializes (+75 basis point on the 5-year mortgage rate), and assuming historically average income growth, prices would need to fall on the order of 2% to keep home affordability from deteriorating further.”

Bank of Canada Rate Announcement Oct 29th, 2025

By Lisa Manwaring • October 29, 2025
Bank of Canada lowers policy rate to 2¼%. FOR IMMEDIATE RELEASE Media Relations Ottawa, Ontario October 29, 2025 The Bank of Canada today reduced its target for the overnight rate by 25 basis points to 2.25%, with the Bank Rate at 2.5% and the deposit rate at 2.20%. With the effects of US trade actions on economic growth and inflation somewhat clearer, the Bank has returned to its usual practice of providing a projection for the global and Canadian economies in this Monetary Policy Report (MPR). Because US trade policy remains unpredictable and uncertainty is still higher than normal, this projection is subject to a wider-than-usual range of risks. While the global economy has been resilient to the historic rise in US tariffs, the impact is becoming more evident. Trade relationships are being reconfigured and ongoing trade tensions are dampening investment in many countries. In the MPR projection, the global economy slows from about 3¼% in 2025 to about 3% in 2026 and 2027. In the United States, economic activity has been strong, supported by the boom in AI investment. At the same time, employment growth has slowed and tariffs have started to push up consumer prices. Growth in the euro area is decelerating due to weaker exports and slowing domestic demand. In China, lower exports to the United States have been offset by higher exports to other countries, but business investment has weakened. Global financial conditions have eased further since July and oil prices have been fairly stable. The Canadian dollar has depreciated slightly against the US dollar. Canada’s economy contracted by 1.6% in the second quarter, reflecting a drop in exports and weak business investment amid heightened uncertainty. Meanwhile, household spending grew at a healthy pace. US trade actions and related uncertainty are having severe effects on targeted sectors including autos, steel, aluminum, and lumber. As a result, GDP growth is expected to be weak in the second half of the year. Growth will get some support from rising consumer and government spending and residential investment, and then pick up gradually as exports and business investment begin to recover. Canada’s labour market remains soft. Employment gains in September followed two months of sizeable losses. Job losses continue to build in trade-sensitive sectors and hiring has been weak across the economy. The unemployment rate remained at 7.1% in September and wage growth has slowed. Slower population growth means fewer new jobs are needed to keep the employment rate steady. The Bank projects GDP will grow by 1.2% in 2025, 1.1% in 2026 and 1.6% in 2027. On a quarterly basis, growth strengthens in 2026 after a weak second half of this year. Excess capacity in the economy is expected to persist and be taken up gradually. CPI inflation was 2.4% in September, slightly higher than the Bank had anticipated. Inflation excluding taxes was 2.9%. The Bank’s preferred measures of core inflation have been sticky around 3%. Expanding the range of indicators to include alternative measures of core inflation and the distribution of price changes among CPI components suggests underlying inflation remains around 2½%. The Bank expects inflationary pressures to ease in the months ahead and CPI inflation to remain near 2% over the projection horizon. With ongoing weakness in the economy and inflation expected to remain close to the 2% target, Governing Council decided to cut the policy rate by 25 basis points. If inflation and economic activity evolve broadly in line with the October projection, Governing Council sees the current policy rate at about the right level to keep inflation close to 2% while helping the economy through this period of structural adjustment. If the outlook changes, we are prepared to respond. Governing Council will be assessing incoming data carefully relative to the Bank’s forecast. The Canadian economy faces a difficult transition. The structural damage caused by the trade conflict reduces the capacity of the economy and adds costs. This limits the role that monetary policy can play to boost demand while maintaining low inflation. The Bank is focused on ensuring that Canadians continue to have confidence in price stability through this period of global upheaval. Information note The next scheduled date for announcing the overnight rate target is December 10, 2025. The Bank’s next MPR will be released on January 28, 2026.

What Are GDS/TDS Ratios Anyways?

By Lisa Manwaring • October 22, 2025
One of the major qualifiers lenders look at when considering your application for mortgage financing is your debt service ratios. Now, before we get started, if you prefer to have someone walk through these calculations with you, assess your financial situation, and let you know exactly where you stand, let’s connect. There is no use in dusting off the calculator and running the numbers yourself when we can do it for you! However, if you’re someone who likes to know the nitty-gritty of how things work instead of simply accepting that's just the way it is, this article is for you. But be warned, there are a lot of mortgage words and some math ahead; with that out of the way, let’s get started! “Debt servicing” is the measure of your ability to meet all of your financial obligations. There are two ratios that lenders examine to determine whether you can debt service a mortgage. The first is called the “gross debt service” ratio, or GDS, which is the percentage of your monthly household income that covers your housing costs. The second is called the “total debt service” ratio, or TDS, which is the percentage of your monthly household income covering your housing costs and all your other debts. GDS is your income compared to the cost of financing the mortgage, including your proposed mortgage payments (principal and interest), property taxes, and heat (PITH), plus a percentage of your condo fees (if applicable). Here’s how to calculate your GDS. Principal + Interest + Taxes + Heat / Gross Annual Income Your TDS is your income compared to your GDS plus the payments made to service any existing debts. Debts include car loans, line of credit, credit card payments, support payments, student loans, and anywhere else you’re contractually obligated to make payments. Here’s how to calculate your TDS. Principal + Interest + Taxes + Heat + Other Debts / Gross Annual Income With the calculations for those ratios in place, the next step is to understand that each lender has guidelines that outline a maximum GDS/TDS. Exceeding these guidelines will result in your mortgage application being declined, so the lower your GDS/TDS, the better. If you don’t have any outstanding debts, your GDS and TDS will be the same number. This is a good thing! The maximum ratios vary for conventional mortgage financing based on the lender and mortgage product being offered. However, if your mortgage is high ratio and mortgage default insurance is required, the maximum GDS is 39% with a maximum TDS of 44%. So how does this play out in real life? Well, let’s say you’re currently looking to purchase a property with a payment of $1700/mth (PITH), and your total annual household income is $90,000 ($7500/mth). The calculations would be $1700 divided by $7500, which equals 0.227, giving you a gross debt service ratio of 22.7%. A point of clarity here. When calculating the principal and interest portion of the payment, the Government of Canada has instituted a stress test. It requires you to qualify using the government's qualifying rate (which is higher), not the actual contract rate. This is true for both fixed and variable rate mortgages. Now let’s continue with the scenario. Let’s say that in addition to the payments required to service the property, you have a car payment of $300/mth, child support payments of $500/mth, and between your credit cards and line of credit, you’re responsible for another $700/mth. In total, you pay $1500/mth. So when you add in the $1700/mth PITH, you arrive at a total of $3200/mth for all of your financial obligations. $3200 divided by $7500 equals 0.427, giving you a total debt service ratio of 42.7%. Here’s where it gets interesting. Based on your GDS alone, you can easily afford the property. But when you factor in all your other expenses, the TDS exceeds the allowable limit of 42% (for an insured mortgage anyway). So why does this matter? Well, as it stands, you wouldn’t qualify for the mortgage, even though you are likely paying more than $1700/mth in rent. So then, to qualify, it might be as simple as shuffling some of your debt to lower payments. Or maybe you have 10% of the purchase price saved for a downpayment, changing the mortgage structure to 5% down and using the additional 5% to pay out a portion of your debt might be the difference you need to bring it all together. Here’s the thing, as your actual financial situation is most likely different than the one above, working with an independent mortgage professional is the best way to give yourself options. Don’t do this alone. Your best plan is to seek and rely on the advice provided by an experienced independent mortgage professional. While you might secure a handful of mortgages over your lifetime, we do this every day with people just like you. It’s never too early to start the conversation about mortgage qualification. Going over your application and assessing your debt service ratios in detail beforehand gives you the time needed to make the financial moves necessary to put yourself in the best financial position. So if you find yourself questioning what you can afford or if you want to discuss your GDS/TDS ratios to understand the mortgage process a little better, please get in touch. It would be a pleasure to work with you, we can get a preapproval started right away.
