How to sell on Amazon Canada with Amazon US account?

I have been selling on Amazon.com as the seller for few years. Is it possible for me to sell on Amazon Canada using the same seller central account I have in the US? Ideally it would be FBA as well in Canada. I don’t want to deal with the hassle of opening a new company, warehouse and account for Canada if there is an easier way.

Note: my product is in food & grocery category.
