A Calgary man says a water leak and mould in his southeast apartment is the latest in a series of problems with his landlord.

Robert Gaboury says a water leak caused a chunk of ceiling in his bedroom closet to fall down on Dec. 26.

"I was upstairs and I heard it and I came down and opened the door and it clunked me on the head," he said.

Gaboury says he complained, but no one came to fix it until this week — and mould is growing in the closet.

"It's scary, you know, I don't know if I'm going to wake up in the middle of the night or the morning with two or three inches of water soaking up all of my possessions," he said.

Gaboury says he has had similar problems in the past.

Mainstreet Equity, which owns the apartment complex, is currently renovating. Spokesperson Michael Birklein says this can happen in old buildings.

"You can't necessarily forsee this kind of issue, so what we do is as soon as we know there's a problem that's when we act or we do audits throughout the year," he said.

Alberta Health Services says next week it will reinspect work that was done to address the mould concerns.
