Definition

Articles of incorporation

Articles of incorporation are the document filed with a government corporate registry to legally create a corporation. They set the company’s name, the classes of shares it can issue, any restrictions on its business or share transfers, and other foundational rules the corporation operates under.

Reviewed

A corporation does not exist until its articles of incorporation are filed and accepted. The articles are the constitutional document of the company: everything else, from bylaws to shareholder agreements, operates within the framework the articles set up.

What articles typically set out

  • The corporation’s legal name and where its registered or head office is located
  • The classes and maximum number of shares it is authorized to issue
  • Any restrictions on share transfers or on the business the company can carry on
  • The minimum and maximum number of directors

Federal or provincial

A corporation can be incorporated federally or under a specific province’s corporate statute, and the articles are filed with whichever registry applies. The two systems have different forms and some different default rules, so a set of articles filed federally cannot simply be compared line by line with one filed provincially.
