Filling out T2091 when change of use from rental to principle residence
Fact:
I bought a property A in 2015, and I have lived there until Aug 2016 before I rented it out. I recently sold my principle residence B and I moved back to my rental property A in 2023.
Question:
I am preparing my return for 2023. I filled out Schedule 3 and selected option 2 on line 17900. I have also filled out T2091 Section 1 and 2. I am planning to elect S.45(3) for this change, but T2091 is proposing a capital gain on the former rental property A. Did I do something wrong or what should I do so the capital gain can be deferred?
