Top 10 Cities in Canada with Highest Number of Illegal Immigrants – A Data-Led 2025 Snapshot

Canada welcomes millions of newcomers through legal pathways every year. Yet a parallel reality exists: people who fall out of status and keep living and working in our cities. This guide looks at where they are most likely to live, why they’re there, and what local policies mean for access to services. We use “undocumented” as the preferred term, while keeping the SEO phrase Top 10 Cities In Canada With Highest Number of Illegal Immigrants in key spots so readers can find this resource.
Why This Matters Now
- Labour shortages persist in construction, care work, food services, and logistics.
- Policy talks about the regularization and enforcement continuing nationwide.
- Cities carry much of the load: health access, schooling for kids, housing, transit.
How We Ranked the Top 10 Cities In Canada With the Highest Number of Illegal Immigrants
Because undocumented residents aren’t counted directly, we combine:
- Census immigrant share by CMA (as a proxy for inflows/networks)
- Local “access without fear” or sanctuary-style policies
- Media, academic, and service-provider signals about underground work and access barriers
- National estimate range (hundreds of thousands) to keep city estimates conservative and non-specific
Important: Rankings are directional, not exact counts.

Economic Reality vs. Legal Risk
Contributions
- Fills gaps in care, construction, cleaning, delivery, and food services.
- Pays rent, transit, and consumption taxes; stabilizes small businesses.
Risks
- Wage theft and unsafe worksites.
- Limited access to primary care; delayed treatment raises costs later.
- Family separation fears; children’s schooling disrupted by mobility.
Policy Ideas Cities are Testing
- “Access without fear” intake: decouple municipal services from status checks.
- Wage recovery hotlines: support when pay is withheld.
- Community health partnerships: low-barrier clinics, vaccine access.
- School liaison teams: stable enrollment for kids, no matter status.
- Construction & care work audits: focus on safety and fair pay.
What Residents, Employers, and Readers Can Do
- Residents: support local clinics, legal aid, and food banks.
- Employers: verify status, pay fairly, and use legal hiring routes.
- Students/temporary workers: track permit dates; renew early; keep proof of funds/insurance.
- If you lost status: seek a licensed RCIC or lawyer about restoration, TRP, or other options.
The Top 10 Cities In Canada With Highest Number of Illegal Immigrants ranking is a directional map, not a census. It blends statistics, policy cues, and community signals to highlight where solutions matter most.

In that sense, discussing the Top 10 Cities in Canada with the Highest Number of Illegal Immigrants is really about how we keep Canadian cities working for everyone.
