Brother included my personal belongings in sale of his house

Location: Ontario

For context, I lent my brother gym equipment in 2020 or 2021 during the covid lockdowns. I have asked for pieces of it back over the years, but he said he was still using it, and it wasn’t urgent, so I never pushed too hard to get it back.

Recently, he listed one of his properties for sale and asked to borrow some more items (TV, dining table, etc.) to stage the house, as well as, he moved the gym equipment into the empty house for staging.

Well, it has come up that he included the gym equipment in the sale of his house. I’m talking 5k worth of gym equipment (I used to own a gym, I have quite a bit of equipment). I told him that it was mine and he should not have done that. He now claims I sold it to him for $400 during covid.

Closing has not yet happened. His inspections are taking place on Wednesday. What is my recourse here? Do I have any options?
