MONTREAL -- The mystery of the monoliths has made its way to Montreal.

A tall silver structure is currently standing, screwed in place to the sidewalk, on Sherbrooke St. W at the corner of Wilson Ave. in Notre-Dame-de-Grace.

A spokesperson for the borough said the monolith appears to be on private property and therefore has no plans to remove it. Montreal police said they were unaware of the monolith until CTV News reached out for comment. 

Similar structures have been popping up in locations all over the world since the first one was discovered in the Utah desert last month and days later, a similar structure appear on a Romanian hilltop.

The monoliths have caused a stir on social media, many confounded by how they got there and why.
