TORONTO, ON — November 6, 2025— Rat sightings are surging across major Canadian cities, and new data confirms the rise is both real and widespread. A national survey conducted by Abell Pest Control during last month’s Canadian Institute of Public Health Inspectors (CIPHI) conference in Kelowna found that 89% of health inspectors have observed increased rat activity over the past three years.
The findings mirror a growing body of evidence: municipal reports, public complaints, health inspectors’ insights, and Abell’s own data all point to an almost 15% increase in rat activity nationwide over the past three years, driven by breeding cycles, construction disruptions, and the abundance of urban food sources.
“Rats are highly adaptable and thrive in urban environments,” explained Aaron Soudant, Director of Service Excellence and Quality Assurance at Abell Pest Control. “With changing weather, construction activity, and easy access to food sources, conditions are ideal for rats to survive and multiply year-round, making proactive prevention essential for every community.”
Why the Increase?
Construction and pandemic-era disruptions displaced rat populations, pushing them into new neighbourhoods where they’ve since established themselves. Warmer winters now extend breeding seasons, while accessible food sources, garbage, compost, bird seed, pet food, and commercial waste, sustain larger colonies. Aging infrastructure, foundation gaps, and ongoing urban development further contribute to ideal nesting and entry conditions.
The pattern is consistent across the country: Brampton residents report daily sightings in previously unaffected areas, Toronto has launched a coordinated rat-response initiative, Montréal is managing a spike in complaints, and Vancouver and Ottawa both link growing infestations to heavy construction and milder winters.
A Growing Public Health Priority
On average, activity has risen roughly 15% in the past three years, with 60% of health inspectors confirming a steady upward trend across most industries inspected. Abell Pest Control is urging immediate prevention efforts to curb infestations before they spread further.
“Taking proactive steps now is essential,” Soudant added. “It protects public health, preserves property value, and prevents small problems from becoming costly community issues.”
