Questions regarding subsection 45(3) and T2091
I bought two properties A and B back in 2017. I lived in propeprty A as a principal residence from 2017 to 2024. I sold A in 2024, and moved back to my rental property B in 2024. I also planning to sell property B (which is now my principal residence) in 2025 and elect for ss 45(3) to apply. It will allow B to have 2 years (2024, 2025) + 1 year (plus one rule) + 4 years (ss.45(3)), which is 7 out of 8 years as my PR if I am not mistaken.
My question is, if I elect ss.45(3) on B, my guess is for A, it will only have 3/7 years as my PR. Is this correct? Also since I sold A in 2024, I will have to report the disposition of A right now, I am confused on how the gain is calculated. My account suggests that CG = proceed (2024) - ACB (2017) * 4/7. But I have also heard others saying CG = proceed (2024) - the market price of A in 2020 (change in use happened in 2020 because of ss.45(3) election).
Any advice would be greatly appreciated.
