Coquitlam residents who don't follow the city's garbage rules could soon be fined $150, as officials try to keep hungry bears out of local neighbourhoods.

The city says residents reported 50 bears in May but 98 in June, and of those, 12 bruins were munching on garbage and two were aggressive.

Officials say they want residents to secure their garbage in wildlife-resistant enclosures or by using a city-approved lock, and set their carts on the street between 5:30 a.m. and 7:30 a.m. on collection day.
