Moved from Ontario to Quebec - question on T4/RL1

[marie-aprieto]

I moved from Ontario to Quebec during the year, while staying with the same employer. I have received two T4s  (one for ON, one for QC) from my employer, along with one RL-1. 

When entering my ON T4, an RL-1 is automatically added by the system. Should I and can I remove it? 

Thanks for your help!
