When Thamara DeVries handed over the keys to her fully furnished home in February, she thought she was renting it to a family of four.
But shortly after move-in day, DeVries was called to help with the property's hot tub.
"I realized that there was a mom and a dad and 10 children, which is definitely not what we agreed on," DeVries told CBC News.
She said the couple confirmed the 10 children were all theirs and were all living in the house
That began a months-long effort to evict the tenants. She said the legal process has dragged on, and in the meantime, she's watched the home deteriorate.
"That process has been incredibly painful, excruciating and draining, to say the least," she said. "We have a hard time going to bed, and our financial situation has changed quite a bit, including lawyer fees and the fact that they haven't paid any rent since April."
CBC News knocked on the door of the property in an attempt to speak to the renters, but no one answered.
