What should I do with my ex-roomate’s stuff?

r/

Location: Ontario, Canada.

Im a home owner and had a friend move in for a while. After a few years of living together she moved out, we ended on bad terms. After she moved out there were items of hers left behind. I collected them into a box and have been holding on to it because I simply don’t know what to do with it.

Its been well over a year and she has made no effort to retrieve any of her items. In addition, her mail still comes to my address, she makes no effort to contact me for that either.

What do I do at this point? It’s a large box that is taking up space and I want it gone.
