This Is Ridiculous, Please Don't Judge. I'm Just Looking For Honest Advice.

I had bought a house with my ex in 2010. His parents had help us out with the down-payment, and his father remained on the house at 1% (ex and I have split the remainder).

This all said, we had broken up in 2015. We remained friemds for some time and he asked that I keep my name on the house so that he could improve his credit during the time and have the ability to stay on the house himself afterwards.

It is now 2025, I keep asking to come off of the house, he has financial troubles that Im worried will end up with a lein on the house. He currently resides there with his now wife. He also keeps asking me for more time to get caught up on his taxes etc then mentioned that he did not plan to give me anything or the house, that we had bought together and I paid the mortgage on as well for the 5 years we lived there together.

Do I have a leg to stand on at this point, being that its been 10 years of me obviously being taken advantage of? Im renting, Ive rented ever since we had split. For context, I did leave him, we ran a company together and he was unorganized and incredibly hard to run it with, and I eventually had enough all around and moved into my parents rental.

For context, we were engaged, never married (common-law), the house was bought in Ontario.

Really appreciate any advice here.

Quick edit, I'm looking for advice or thoughts on if I'm still entitled to anything after 10 years. I'm also wondering how I go aboit getting off the house now when he won't make any effort still. Thanks everyone.
