Ontario's environment ministry says it is aware of reports of an odor in the Sault Ste. Marie area on March 26 and has contacted local industrial facilities, including Algoma Steel, as part of its investigation. Ministry staff responded to the area, but the cause of the odor remains unknown at this time.

Why it matters

The ministry's involvement and follow-up with local companies suggests they take these reports seriously and want to identify the source to address any potential public health or safety concerns.
