BREAKING: Canadian Sault lock closed due to 'mechanical issue'

A mechanical issue has impacted the hydraulic systems that open and close the gates at the Sault Ste. Marie Canal National Historic Site recreational lock.

As a result, Parks Canada said Thursday it has closed the recreational lock effective immediately and is investigating the cause and exploring solutions for repairs.

No timeline for reopening is currently available, Parks Canada said in a release.

"Parks Canada recognizes this temporary closure impacts water-based visitation to the national historic site, and appreciates the understanding from visitors," the federal agency said.

"Land-based visitation remains largely unchanged. Until the site closes for the season on Oct. 15, visitors are invited to explore the exhibits in the visitor centre, reserve their Tour with an expert, rent a fat bike, or explore the trail network.

"Access to the grounds, South St. Mary’s Island, and Whitefish Island will not be affected during this temporary lock closure.

"The Soo Locks on the Michigan side of the St. Mary’s River are open and can be used by recreational boaters and tourism operators.

"There are no fees to pass through the Soo Locks, nor need to report with Customs for transient boaters who are not planning to moor or disembark their vessels."

Parks Canada said it will communicate further updates as more information about the mechanical issue and repair timeline becomes available.
