Emterra, which holds the City of Winnipeg's garbage and recycling collection contract, could be penalized by the city if it is not caught up by then. A deadline of 6 p.m. CT was originally set last week.

As of 5:30 p.m. Sunday, garbage collectors were making good progress but some streets in St. Vital may still need to get their yard waste picked up, city officials told CBC News.

The city says it will be cross-checking a list of streets after 7 p.m., when crews were expected to be finished.

Emterra has been struggling to keep up since a new collection system took effect across Winnipeg at the beginning of this month.

The city says its 311 hotline has fielded more than 5,400 "calls of service deficiencies" regarding the garbage collection service since Oct. 1.

If the deadline is not met, the city says it will look at some penalty options, such as hiring another company to finish the job and billing Emterra for the work.
