Dateline: Ottawa – A new analysis of Canada’s ten provinces shows household food insecurity climbing year after year, wiht the share of households affected rising from 16.8% in 2019 to 18.4% in 2022 and 22.9% in 2023. Researchers traced how vulnerability shifted across different income groups and demographic profiles,using data from the Canadian Income Survey.
What the study did
Researchers used master files from the provinces’ households for the 2018, 2021, and 2022 cycles of the Canadian Income Survey. They ran year-specific logistic regression models to estimate the predicted probability of household food insecurity by sociodemographic and economic characteristics. The predicted probabilities were then plotted against each household’s income from the previous tax year, expressed in 2022 constant dollars and adjusted for household size.
Key findings
Across the board,the likelihood of food insecurity rose significantly for most households between 2019 and 2023,regardless of the chosen sociodemographic or economic characteristics. In 2019 and 2022, households deriving at least half of thier income from employment or self-employment faced lower risks than those with a smaller share from work. That protective effect disappeared in 2023.
Additionally, the study found that the probability of food insecurity was markedly higher in 2022 than in 2019 for all households with income above $20,000, and by 2023 the risk had risen across the entire income spectrum compared with 2022.
Interpretation
Experts say the most vulnerable-low-income households-continue to bear the highest risk. However, the gap is narrowing as food insecurity becomes more common among households with moderate and higher incomes, and the dependence on employment income no longer shields families from vulnerability.
Table: Snapshot of trends
| Year | National Food Insecurity Rate | Employment Share Effect (Lower Risk in 2019 & 2022) | 2023 Shift |
|---|---|---|---|
| 2019 | Baseline 16.8% | Households with 50%+ income from employment had lower risk | protective effect observed |
| 2022 | 18.4% | Protective effect persisted for employment-heavy households, but higher overall risk at income > $20k | Risk higher across income levels above $20k |
| 2023 | 22.9% | no difference between employment-heavy and othre households | Risk rising across the entire income spectrum |
Evergreen context
The study’s pattern mirrors broader concerns about rising living costs and the limits of wage-based protection against hunger. As food prices, housing costs, and other essentials shift, even households with stable employment may face greater vulnerability. Policymakers and community organizations may need to reassess safety nets, income supports, and access to affordable groceries to counter a trend that appears to be widening beyond the lowest income brackets.
What this means for households
For families across Canada, the headline rise signals growing pressure from everyday costs. The data emphasize that employment income alone is no longer a guaranteed shield from food insecurity, especially for those in the middle of the income ladder. This attrition of protection highlights the importance of complete strategies that address both earnings and the affordability of basic necessities.

*Source: Statistics Canada, *Household Food Security Survey (2024 release).
The upward trajectory reflects a 8 % increase in food‑insecure households over five years, with the steepest rise observed between 2021 and 2022 when inflation peaked at 8.1 % (Bank of Canada, 2022).
2. Socio‑Economic Vulnerability Shifts
2.1 Declining Protective Role of Employment Income
- Employment‑related income historically accounted for roughly 40 % of a household’s food‑security buffer (Employment Insurance and regular wages).
- Between 2019 and 2023, the protective effect fell to 28 %, driven by:
- Rise in precarious contracts – gig work, zero‑hour contracts, and short‑term temp positions grew by 22 % (Canadian Labour Force Survey, 2023).
- Stagnant real wages – average hourly earnings increased only 1.3 % after inflation adjustment (Statistics canada, 2023).
- Reduced eligibility for Canada‑EI – eligibility criteria tightened in 2021, excluding manny low‑income workers.
2.2 Emerging Vulnerability Indicators
Indicator
2019 Value
2023 Value
% Change
Low‑income households (< $25 k/yr)
13.0 %
15.4 %
+18 %
Single‑parent families

Rural households (non‑urban)
11.2 %
13.8 %
+23 %
These figures illustrate the broadening of risk beyond traditional low‑wage earners to include single parents,Indigenous communities,and rural families facing limited market access.
3. The Inflation‑food Price Nexus
- Food Price Index (FPI) surged from 102 (2019) to 144 (2022) – a 41 % increase (Statistics Canada, 2023).
- Core staples such as fresh produce, dairy, and meat rose at 35‑45 % year‑over‑year, outpacing the 10 % average wage growth.
- Regional disparities: Atlantic provinces recorded the highest per‑capita food cost rise (+48 %), while the Prairies saw a slightly lower increase (+35 %).
Practical tip: households that adopted bulk buying through cooperative grocery groups reported a 12 % reduction in monthly food spend (Food Banks Canada, 2023 case study).
4. Employment Income as a Diminishing Safety Net
4.1 The Role of Stable Full‑Time Work
- Full‑time,permanent positions still provide the strongest shield: 63 % of such households remained food secure in 2023 (Statistics Canada).
- However,the growth of part‑time and contract work reduced the proportion of households with stable income from 45 % (2019) to 31 % (2023).
4.2 Government Interventions and Their Limits
Program
2020‑2023 Disbursement
Effect on Food Insecurity
Canada Emergency Response Benefit (CERB)
$81 B total
Temporary dip in food‑insecure rates (down 1.2 % in 2020)
Canada Child Benefit (CCB) increase (2022)
$13 B additional
Marginal improvement for families with children under 12 (down 0.4 %)
canada Workers Benefit (CWB) expansion (2021)
$1.5 B
Minimal impact; eligibility thresholds still exclude many gig workers
The short‑term nature of CERB and modest size of CCB/CWB adjustments failed to offset the long‑term erosion of employment‑based income security.
5. Real‑World Case Studies
5.1 Vancouver’s “Community Food Hub” Initiative
- launched in 2021, the hub aggregates surplus produce from local farms, distributes it through low‑cost membership plans, and provides job‑training for unemployed youth.
- Outcome: Participating households reported a 15 % drop in food‑insecurity scores within six months (City of Vancouver Social Services Report, 2022).
5.2 Ontario’s “Rapid Response Food Assistance program” (RRFAP)
- Piloted in 2022 across three Northwestern Ontario towns, the program matches unemployment benefits with food vouchers redeemable at local grocers.
- Impact: Food‑bank visits fell by 22 % and the proportion of households reporting “often skipping meals” decreased from 9 % to 5 % (Ontario Ministry of Health,2023).
5.3 Indigenous Communities – The “Northern Food Sovereignty Project”
- In Nunavut (2023),community‑lead fisheries cooperatives supplied fresh fish to remote households,cutting reliance on expensive imported food.
- Result: Household food‑insecurity rates dropped from 28 % to 21 % over a 12‑month period (Indigenous Services Canada Evaluation, 2024).
6. Practical Strategies for households Facing Food insecurity
- Leverage Government Benefits
- Verify eligibility for the Canada Workers Benefit and Ontario Works (or provincial equivalents).
- Apply for provincial nutrition supplements (e.g.,BC’s “Food and Nutritional Services”).
- Optimize Grocery Spending
- Plan weekly menus around sales and seasonal produce.
- Use price‑comparison apps (flipp, Instacart) to locate the lowest‑priced items.
- Participate in Community Food Programs
- Join food co‑ops, community gardens, or local surplus food redistribution networks.
- Volunteer at food banks to gain discounted grocery vouchers (many banks offer this to volunteers).
- Boost Income Resilience

growing Food Insecurity in Canadian Households (2019‑2023): Shifting Socio‑Economic Vulnerability and the Decline of Employment Income as a Protective Factor
1. Recent Trends in Canadian Food Insecurity
| Year | Percentage of Households Experiencing Food Insecurity | Key Drivers |
|---|---|---|
| 2019 | 10.5 % | Baseline pre‑pandemic levels |
| 2020 | 12.3 % | COVID‑19 lockdowns, loss of seasonal work |
| 2021 | 13.1 % | Inflation spikes,reduced child benefits |
| 2022 | 14.7 % | Record‑high food price index, supply chain bottlenecks |
| 2023 | 15.4 % | Persistent wage stagnation, higher utility costs |
*Source: Statistics Canada, *Household Food Security Survey (2024 release).
The upward trajectory reflects a 8 % increase in food‑insecure households over five years, with the steepest rise observed between 2021 and 2022 when inflation peaked at 8.1 % (Bank of Canada, 2022).
2. Socio‑Economic Vulnerability Shifts
2.1 Declining Protective Role of Employment Income
- Employment‑related income historically accounted for roughly 40 % of a household’s food‑security buffer (Employment Insurance and regular wages).
- Between 2019 and 2023, the protective effect fell to 28 %, driven by:
- Rise in precarious contracts – gig work, zero‑hour contracts, and short‑term temp positions grew by 22 % (Canadian Labour Force Survey, 2023).
- Stagnant real wages – average hourly earnings increased only 1.3 % after inflation adjustment (Statistics canada, 2023).
- Reduced eligibility for Canada‑EI – eligibility criteria tightened in 2021, excluding manny low‑income workers.
2.2 Emerging Vulnerability Indicators
| Indicator | 2019 Value | 2023 Value | % Change |
|---|---|---|---|
| Low‑income households (< $25 k/yr) | 13.0 % | 15.4 % | +18 % |
| Single‑parent families | 8.2 % | 10.6 % | +29 % |
| Indigenous households reporting food insecurity | 17.5 % | 22.3 % | +27 % |
| Rural households (non‑urban) | 11.2 % | 13.8 % | +23 % |
These figures illustrate the broadening of risk beyond traditional low‑wage earners to include single parents,Indigenous communities,and rural families facing limited market access.
3. The Inflation‑food Price Nexus
- Food Price Index (FPI) surged from 102 (2019) to 144 (2022) – a 41 % increase (Statistics Canada, 2023).
- Core staples such as fresh produce, dairy, and meat rose at 35‑45 % year‑over‑year, outpacing the 10 % average wage growth.
- Regional disparities: Atlantic provinces recorded the highest per‑capita food cost rise (+48 %), while the Prairies saw a slightly lower increase (+35 %).
Practical tip: households that adopted bulk buying through cooperative grocery groups reported a 12 % reduction in monthly food spend (Food Banks Canada, 2023 case study).
4. Employment Income as a Diminishing Safety Net
4.1 The Role of Stable Full‑Time Work
- Full‑time,permanent positions still provide the strongest shield: 63 % of such households remained food secure in 2023 (Statistics Canada).
- However,the growth of part‑time and contract work reduced the proportion of households with stable income from 45 % (2019) to 31 % (2023).
4.2 Government Interventions and Their Limits
| Program | 2020‑2023 Disbursement | Effect on Food Insecurity |
|---|---|---|
| Canada Emergency Response Benefit (CERB) | $81 B total | Temporary dip in food‑insecure rates (down 1.2 % in 2020) |
| Canada Child Benefit (CCB) increase (2022) | $13 B additional | Marginal improvement for families with children under 12 (down 0.4 %) |
| canada Workers Benefit (CWB) expansion (2021) | $1.5 B | Minimal impact; eligibility thresholds still exclude many gig workers |
The short‑term nature of CERB and modest size of CCB/CWB adjustments failed to offset the long‑term erosion of employment‑based income security.
5. Real‑World Case Studies
5.1 Vancouver’s “Community Food Hub” Initiative
- launched in 2021, the hub aggregates surplus produce from local farms, distributes it through low‑cost membership plans, and provides job‑training for unemployed youth.
- Outcome: Participating households reported a 15 % drop in food‑insecurity scores within six months (City of Vancouver Social Services Report, 2022).
5.2 Ontario’s “Rapid Response Food Assistance program” (RRFAP)
- Piloted in 2022 across three Northwestern Ontario towns, the program matches unemployment benefits with food vouchers redeemable at local grocers.
- Impact: Food‑bank visits fell by 22 % and the proportion of households reporting “often skipping meals” decreased from 9 % to 5 % (Ontario Ministry of Health,2023).
5.3 Indigenous Communities – The “Northern Food Sovereignty Project”
- In Nunavut (2023),community‑lead fisheries cooperatives supplied fresh fish to remote households,cutting reliance on expensive imported food.
- Result: Household food‑insecurity rates dropped from 28 % to 21 % over a 12‑month period (Indigenous Services Canada Evaluation, 2024).
6. Practical Strategies for households Facing Food insecurity
- Leverage Government Benefits
- Verify eligibility for the Canada Workers Benefit and Ontario Works (or provincial equivalents).
- Apply for provincial nutrition supplements (e.g.,BC’s “Food and Nutritional Services”).
- Optimize Grocery Spending
- Plan weekly menus around sales and seasonal produce.
- Use price‑comparison apps (flipp, Instacart) to locate the lowest‑priced items.
- Participate in Community Food Programs
- Join food co‑ops, community gardens, or local surplus food redistribution networks.
- Volunteer at food banks to gain discounted grocery vouchers (many banks offer this to volunteers).
- Boost Income Resilience
- Pursue skill‑based training through Canada‑Skill Canada’s free online courses.
- Explore remote freelance platforms that provide higher pay stability than gig‑economy apps.
- Monitor Household Food Security
- Use the HFSSM (Household Food Security survey Module) self‑assessment tool (available on the Government of canada website) to track changes and trigger assistance early.
7.Policy Recommendations for Reducing Vulnerability
| Recommendation | Rationale | Expected Impact |
|---|---|---|
| Raise the minimum wage to a living‑wage index (adjusted annually for inflation) | Directly increases employment income, strengthening its protective role | Potential 6‑8 % reduction in national food‑insecurity prevalence |
| Expand eligibility for the Canada workers Benefit to include gig workers | Addresses the growing precarious‑work segment | Estimated 4 % drop in food‑insecure households among 18‑34 year‑olds |
| Invest in regional food hubs and transportation infrastructure | Reduces cost of fresh foods in rural and remote areas | Improves food‑access scores for Indigenous and Northern communities |
| Implement a national food‑price stabilization fund | Mitigates sharp spikes in staple prices | Buffers low‑income households from inflation‑driven food cost shocks |
| Integrate food‑security screening into employment‑insurance and unemployment services | Early identification of at‑risk households | Faster referral to nutrition assistance, reducing “skip‑meal” incidents |
8. Key Takeaways for Readers
- Employment income is no longer a reliable safety net; precarious work, stagnant wages, and inflation have eroded its protective capacity.
- Food insecurity is rising across all demographics,with single‑parent families,Indigenous households,and rural communities facing the steepest increases.
- Community‑driven initiatives (food hubs, voucher programs, sovereignty projects) demonstrate measurable success and should be scaled.
