How much of household income goes to keeping a roof overhead — measured at Canada's traditional 30% affordability line, and at the 40%-of-income threshold the OECD and Eurostat use to compare countries on a common basis.

Homebuying affordability — the cost of entering the market (mortgage payment + down payment on a newly bought home), distinct from this measure of the ongoing cost for those already housed.
Housing affordability is usually framed around a single rule of thumb: a household is "burdened" when shelter costs pass 30% of income. Canada has used that line since the mid-1980s, when the Canada Mortgage and Housing Corporation adopted it with the provinces to define housing need, and it remains the backbone of the census and of the official measure of core housing need. By that yardstick, one in five Canadian households was over the line in 2021 — and the burden falls far more heavily on renters than owners.
The 30% line, however, is a North American convention. The OECD and Eurostat instead count households spending more than 40% of disposable income on housing as "overburdened," which is the basis on which countries can actually be compared. This page leads with that 40% measure for cross-country comparability, and reports Canada's familiar 30% figures alongside it.
Over the 30% line · 2021
20.9%
Share of Canadian households spending 30%+ of income on shelter, down from 24.1% in 2016 (Census).
Renters over 30% · 2021
33.2%
More than double the 14.8% rate for owner households — the burden is concentrated among renters.
OECD overburden (>40%) · 2022
8%
Canada's internationally comparable rate — close to the EU average of 8.2%, but ~35% among low-income households.
The internationally comparable picture
On the common 40%-of-disposable-income measure, Canada does not stand out as an outlier: at roughly 8% of the population overburdened (2022), it sits right at the EU-27 average of 8.2% and below Germany (12.0%), though above France (7.0%) and Italy (5.1%). That is a genuinely useful corrective to the domestic narrative — but it comes with an important caveat. This flow measure captures the ongoing cost of rent and mortgage relative to income; it says little about the price of entry. Canada's affordability problem shows up most acutely in house-price-to-income ratios and down-payment hurdles rather than in the monthly cost-to-income ratio of those already housed, and the OECD figure for Canada counts only rent and mortgage, not the wider housing costs (utilities, taxes, upkeep) included in the European figures — so Canada's 8% is, if anything, understated against the European bars.
Housing cost overburden rate — share of population spending more than 40% of disposable income on housing (%), Canada vs the European G7 and the EU-27 average
Source: France, Germany, Italy, and the EU-27 average — Eurostat, housing cost overburden rate (ilc_lvho07a), 2024, total housing costs net of allowances. Canada — OECD Affordable Housing Database, indicator HC1.2 (2025 release), 2022 (Canada Income Survey), rent + mortgage basis. Both apply the same >40%-of-disposable-income threshold, but the cost bases differ (see methodology), so Canada's bar is a close reference point rather than a strict like-for-like. The non-European G7 members — the United States, United Kingdom, and Japan — are published by the OECD only on the rent-and-mortgage basis within its source spreadsheet and are not yet shown; adding them on a single consistent basis is the next refinement (see ledger).
Two thresholds, two stories. At the 40% line used for international comparison, Canada looks middling. At Canada's own 30% line, one in five households is over — and a third of renters. The gap is not a contradiction: it reflects where the threshold is drawn and that the affordability strain is concentrated among renters and would-be buyers, not the average mortgage holder.
Canada's 30% measure over time
The Canadian Housing Survey tracks the 30% threshold annually. The share of households over the line dipped through the pandemic — when income supports and low rates eased the squeeze — then rose again in 2022 as rents and renewal rates climbed. Throughout, renters are over the line at roughly twice the rate of owners, and within the owner group it is those carrying a mortgage who feel it.
Share of households spending 30% or more of income on shelter costs, by tenure (%), Canada
Source: Statistics Canada, Canadian Housing Survey 2018, 2021, and 2022 (Table 5269; The Daily, 10 September 2024). Note the survey-based CHS figures differ slightly from the 2021 Census (20.9% all households) owing to different methodologies.
The 2021 Census, which covers every household rather than a survey sample, tells the same tenure story in sharper relief: 40.0% of renters were over the 30% line in 2016, easing to 33.2% in 2021, against 16.6% → 14.8% for owners. The strain is also highly regional — in 2021 it reached 30.5% of households in Toronto and 29.8% in Vancouver, against the 20.9% national figure.
Findings
Finding 1
One in five households is over the affordability line
20.9% of Canadian households spent 30%+ of income on shelter in 2021, down from 24.1% in 2016 — improvement driven mostly by low pandemic-era interest rates rather than by housing becoming cheaper.
Finding 2
The burden is a renter problem
Renters were over the 30% line at 33.2% in 2021 — more than double the 14.8% owner rate. In market rental housing the Canadian Housing Survey put the 2022 figure at 34.0%.
Finding 3
Internationally, Canada is mid-pack on the flow measure
On the comparable >40%-of-income overburden rate, Canada (~8%, 2022) sits right at the EU-27 average (8.2%) and below Germany (12.0%), though above France (7.0%) and Italy (5.1%) — the strain shows up in prices, not in the monthly cost ratio of those already housed.
Finding 4
The improvement has reversed
After easing to 19.5% in 2021, the share of households over the 30% line climbed back to 22.0% in 2022 as rents and mortgage-renewal costs rose — erasing the pandemic-era gains.
Definitions. The shelter-cost-to-income ratio divides a household's shelter costs by its total income; Canada (CMHC / Statistics Canada) treats 30% of before-tax income as the affordability line. The OECD/Eurostat housing cost overburden rate uses a 40% threshold against disposable (after-tax) income, net of housing allowances. We lead with the 40% measure for cross-country comparability and report the Canadian 30% figures alongside, as agreed.
Comparability. Three caveats apply to the international chart. (a) Threshold: 40% (international) vs 30% (Canadian convention) — the figures are not interchangeable. (b) Cost basis: the Canada OECD figure counts rent and mortgage only; the European figures include wider housing costs (utilities, taxes, maintenance), so Canada's 8% is, if anything, understated against them. (c) Income basis: disposable income internationally vs before-tax income for the Canadian 30% series. The OECD figure also masks distribution — Canada's overburden rate is ~8% across all households but roughly 35% among low-income (bottom-quintile) households.
Why the flow measure understates the crisis. Cost-to-income measures capture households already in their homes. Canada's affordability problem is concentrated in the price of entry (house-price-to-income and deposit requirements) and among renters and would-be buyers, which a flow ratio of existing occupants does not fully register.
