I have been filing taxes in ontario and i recently started working for this montreal office from july 2020. If i receive ITA do i need to stop working for montreal employer? Hoping ITA in this coming draw if its CEC.IMO during this crazy times and remote working Job doesn't matter but where you file your taxes matter and your physical address. Not sure how you have been filing taxes past 2 years while working for montreal employer. If it was ontario then EE should be your choice.
