I moved from US to Canada in Nov 2021. Had some Restricted stock units granted in 2020 and 2021 that got vested during 2022.  My employer has issue me a T4 (under Box 14) including the full FMV as on vesting date, W-2 (for US) was also issued.

W.r.t the taxation of the RSU's income that are granted in 2020/2021 but vested in 2021, how are these to be taxed from Canada perspective

1. Would the entire amount be taxed in Canada (since its on T4) and a foreign Tax credit be taken for the US taxes.

2. Would the RSU amount be split into 2 portions   based on no. of work days in Canada divided by total holding period [grant to vest date] and be taxed only for the Canada specific percentage
