Before you start
For income tax purposes, the CRA defines a business as an activity where there is a reasonable expectation of profit and there is evidence to support that intention. For goods and services tax / harmonized sales tax (GST/HST) purposes, a business also includes any activity whether or not it is carried on for profit, and any regular or continuous activity that involves supplying property by way of lease, licence, or similar arrangement.
If you are starting a new small business, go to Setting up your business to make sure you do everything you need. This page includes information about your business' structure as well as registering your business for the first time.
