Work on a major highway expansion project north of Toronto has continued on schedule throughout the COVID-19 pandemic.

Ontario Minister of Transportation Minister Caroline Mulroney visited the site for a construction update on Labour Day weekend.

“Highway 427 has been operating well beyond its capacity for many years and the expansion project is well underway,” Mulroney wrote on Twitter.
