Incorporation can be done at the federal or provincial/territorial level. When you incorporate your business, it is considered to be a legal entity that is separate from its shareholders. As a shareholder of a corporation, you will not be personally liable for the debts, obligations or acts of the corporation. It is always wise to seek legal advice before incorporating.
