I made the phone calls a year or two ago because I was getting conflicting information. Friends in our business insisted we need a BIN and my daycare Mom who works at Canada Revenue told me I don't need it.

Here is what I found out:

A small business that earns over $30,000. and has an employee are the only ones who need a Business Number. (1-800-959-5525) This is Federal and with Revenue Canada. Our businesses are HST & GST free so again we don't have to worry about this.

Buiness Identification Number (BIN) is provincial and is only $60 for 5 years and is helpful so that you don't have to give out your SIN on your receipts, etc. Services Ontario 1-888-745-8888

So Reggio is right that you may have to contact your own provincial govmt.
