This Is Where Mice Thrive in Toronto According to an Exterminator

An exterminator company in the Greater Toronto Area has identified the top 10 intersections most impacted by mice infestations based on its recorded service requests and call volumes.
Pest control company GTA Exterminators says mice are becoming more common in Toronto, noting that it experienced an increase in mice-related calls between August 2024 and July 2025.
“The company reports that calls related to mice increased by 35% compared to last year, underscoring the growing rodent challenge facing the city,” an Aug. 29 news release says.
The Toronto intersections with the highest reported mouse activity according to GTA Exterminators include:

Caledonia Road & Rogers Road
Lawrence Avenue West & Avenue Road
Mount Pleasant Road & St. Clair Avenue East
O’Connor Drive & Woodbine Avenue
Don Mills Road & Eglinton Avenue East
Bloor Street West & Parkside Drive
Keele Street & Sheppard Avenue West
The Bridle Path & Lawrence Avenue East
Lawrence Avenue West & Bathurst Street
Yonge Street & Bloor Street

GTA Exterminators account manager John Voss says Toronto’s urban density and older infrastructure provide mice with the “perfect conditions” to thrive. He says the company is receiving more mice-related calls from busy intersections and residential areas than ever before….
