Local officials told CBC News wind pushed built-up ice off Dauphin Lake Friday onto nearby homes, destroying six homes and damaging 14 others.
No injuries were reported.
The incident happened in the same area that suffered extensive damage by flooding in 2011.
"They're devastated. Most of these people were hit hard during the flood," Clayton Watts, the deputy reeve of the rural municipality of Ochre River, said Friday night. "Most of them were back to the stage where they were back living in their homes again, and now this has happened. So they're pretty devastated right now."
