Once the corporation has been created, a number of other items must be considered. Next steps following incorporation, this link provides information on what needs to be done after a corporation has been created and on how to operate a not-for-profit corporation under the NFP Act.
You will be required to file certain documents with Corporations Canada (see Your reporting obligations under the Canada Not-for-profit Corporations Act).
At the first organizational meeting, the directors can make by-laws. This process can be simplified by referring to the Model by-laws – Not-for-profit corporations, which have been written to apply to a typical not-for-profit corporation.
Corporations Canada has also developed an online interactive tool called a By-law builder: not-for-profit corporations that allows you to generate the by-laws you want by choosing provisions that meet the specific needs of your corporation from a number of available options.
For further support you can look at the resources at the Community Legal Education guide on starting a non profit organization.
