Now, another cut to the limit is on the way.
Starting October 1, households with roadside garbage pickup will only be able to have one bag a week picked up.
Officials with the city are hoping for people to change their habits.
Renee Brownlee is the city’s collection and recycling manager.
"Our study tells us that 91% are participating in the blue box program, but only 27% of residents are participating in the green cart program. And that's probably where we can make the biggest steps, are to use the green cart and get participation in that." said Brownlee.
Citizens are already limited to two bags a week, but city officials say most are already leaving just one bag.
CTV News spoke to some residents on Wednesday who like the idea in theory, but are concerned at the restrictions.
"I think it's a great idea, however, those that live in huge households, like I'm a student and we live with five other people, so it's a big area to do that with only one garbage."
"It doesn't seem unreasonable, but I know that it would be burdensome on some citizens, myself included. Often, I find I go way over one bag."
"Two bags sometimes is a little bit much, but one bag too can easily be not enough, depending on if you're a family of 5."
