The governing statute depends on where you incorporated. A federal non-profit is created and run under the Canada Not-for-profit Corporations Act (S.C. 2009, c. 23), administered by Corporations Canada, and the by-law power lives in section 152: unless the articles, by-laws or a unanimous member agreement say otherwise, the directors may make, amend or repeal a by-law by resolution, but they must then submit that change to the members at the next meeting, where the members confirm, reject or amend it by ordinary resolution. A by-law that the directors never put to the members ceases to have effect. That confirmation mechanic is the single most misunderstood feature of federal governance, and it shapes how the amendment article of any compliant by-law has to read.
Provincial corporations follow parallel statutes. Ontario non-profits run under the Not-for-Profit Corporations Act, 2010 (ONCA), British Columbia entities under the Societies Act, and Alberta clubs under the Societies Act or the Companies Act depending on form. These statutes set defaults the by-laws can refine but not override, including director qualifications, members' rights to call meetings and the quorum rules. A useful detail many boards miss: under ONCA, if the directors fail to pass an organisational by-law within sixty days of incorporation, the corporation is deemed to have adopted the Director's standard by-laws, which rarely fit a real organisation.
Charitable status is a separate layer that sits on top of the corporate form. Incorporating does not make you a charity. A corporation must apply to the Canada Revenue Agency to be registered, must adopt exclusively charitable purposes, and only then may it issue official donation receipts and must file the annual T3010 return. You can read the federal statute in full on the government's official Justice Laws record of the Canada Not-for-profit Corporations Act. Organisations that also handle members' or donors' personal data must respect PIPEDA or the equivalent provincial privacy law, and our Canadian non-profit and association templates are drafted with these overlapping obligations in mind.
