Toronto Remains Canada's No. 1 Rattiest City

MISSISSAUGA, Ontario - Orkin Canada rattiest cities list saw populous cities Toronto and Vancouver continue to battle it out for first place in the rat race, and welcomed Ottawa, Scarborough and Moncton back to the top 10 list.

"Rat and mice calls used to be expected primarily in the fall and winter as they escape the cold outdoors, but now they are becoming a year-round effort," said Dr. Alice Sinia, pest specialist and entomologist with Orkin Canada. "Longer summer seasons coupled with abundant food sources provide ideal conditions for exponential growth in rodent populations, which is why it is more important than ever to use integrated pest management techniques to tackle all of the conditions that allow mice and rats to proliferate."

City rankings are based on the number of commercial and residential rodent (rat and mice) treatments that Orkin Canada carried out from Aug. 1, 2022, through July 31, 2023.

The top 10 rattiest cities in Canada in 2023 are:

1. Toronto
2. Vancouver
3. Burnaby
4. Kelowna
5. Mississauga
6. Richmond
7. Victoria
8. Ottawa
9. Scarborough
10. Moncton
