Thanks for the reply.It depends on the visa officer examining your application. Some officer might ask proof that you are residing in Ontario and not in Quebec. Most probably you will be fine.
I did my taxes from Ontario and Notice of assessment has Ontario address.
In addition, I asked my HR to include the following in the reference letter,
"Mr ABC, is based of Ontario and remotely working for the organization and will continue to work remotely in future".
Will this help and in addition what IRCC might ask for to show proof of residence, please suggest. I will get ready to show case if they need.
Thanks.
