This post is part of a series on my story incorporating in Canada.
Once you have a corporation registered you will receieve a message (in my case it was a letter) from the Canada Revenue Agency (CRA) with your business number and Canada Revenue Agency (CRA) account number(s) for your business. This is a very important number that you will use in other CRA programs so make sure you have it somewhere safe.
Fill out the form the CRA gives you and send it back to them.
