ONCA Compliance Requirements for Ontario Non-Profits 2026
Reviewed by Bader A. Chowdry, CPA, CA, LPA on
Quick answer: Ontario’s Not-for-Profit Corporations Act, 2010 (ONCA) governs every non-share-capital corporation in the province. Core compliance obligations are: at least 3 directors, at least one class of voting members, an annual members’ meeting, an annual return filed under the Corporations Information Act, board-approved by-laws that conform to ONCA, proper corporate records available to members, and the financial-review tier (audit, review engagement, or waiver) matched to your revenue and public-benefit status.
What does ONCA compliance actually require of an Ontario non-profit board?
ONCA compliance has five recurring pillars: (1) governance structure — at least 3 directors and by-laws that conform to the Act; (2) member rights — at least one voting class, one vote per member at meetings unless articles say otherwise, and member access to financial and corporate records; (3) meetings — a mandatory annual meeting within the timeline set by the corporation’s by-laws; (4) filings — an annual return under the Corporations Information Act plus any Ontario Business Registry updates; and (5) financial review — audit, review engagement, or waiver, scaled to revenue and public-benefit status (see our companion piece on ONCA audit and review-engagement thresholds for the exact dollar tiers).
Most compliance gaps we see in practice aren’t dramatic — they’re administrative drift: by-laws that still reference the old Corporations Act, a board that hasn’t formally re-passed its financial-review waiver resolution in two years, or an annual return that quietly lapsed. None of these trigger an immediate penalty the way a missed CRA deadline does, but they compound: a lapsed annual return can put a corporation into default status with the Ontario Business Registry, which then blocks other filings (including articles of amendment) until resolved.
What are a non-profit board’s core governance obligations under ONCA?
Directors must maintain a board of at least 3 directors (articles can set a higher minimum or a maximum, never lower). For public benefit corporations — charitable corporations, or non-charitable corporations receiving more than $10,000/year from non-member donations or government grants — no more than one-third of directors may be employees of the corporation or its affiliates, a safeguard against a board dominated by paid staff. Directors owe the corporation a duty of care and a duty of loyalty, must act honestly and in good faith, and can face personal liability for breaches — including for skipping a legally required financial review.
What member rights and meeting obligations does ONCA create?
Every corporation must have at least one class of voting members, and each member gets one vote at meetings unless the articles specify otherwise. Members have enhanced rights under ONCA to inspect financial statements, meeting minutes, and other corporate records — a meaningful shift from the prior Corporations Act. An annual meeting of members is mandatory; skipping it, or failing to present financial statements at it, is itself a compliance failure independent of whether an audit or review was otherwise required.
What ongoing filings does ONCA compliance require?
Beyond the corporate statute itself, non-profits must keep their annual return current under the Corporations Information Act through the Ontario Business Registry — this is separate from (and in addition to) the CRA’s T3010 return for registered charities. Corporations that update governing documents, change directors, or amend articles must also file the corresponding notices with the Business Registry. A corporation that falls behind on its annual return risks administrative dissolution over time, which is far more disruptive to unwind than simply filing on schedule.
How does the financial-review requirement fit into overall compliance?
The financial-review tier — audit, review engagement, or waiver — is one compliance pillar among several, and it is the one most boards focus on because it has a hard dollar trigger. A public benefit corporation needs a mandatory audit at $500,000 or more in annual revenue, a review engagement between $100,000 and $500,000 (audit itself waivable), and can waive both at $100,000 or less. Non-public-benefit corporations get a simpler track: waive both at $500,000 or less, review engagement above that. Every waiver — whether of the audit alone or of both — requires an 80% extraordinary resolution and lapses at the next annual meeting, so it must be re-passed yearly if the board wants to keep waiving. We cover the full threshold table and worked examples in our dedicated ONCA audit threshold guide.
Frequently asked questions
Does ONCA apply to all non-profits in Ontario?
ONCA generally applies automatically to every non-share-capital corporation incorporated under an Ontario statute, including those previously governed by the old Corporations Act. Exceptions exist for insurance corporations, co-operative corporations, and certain special-act or private-act corporations — those should confirm applicability with legal counsel.
What happens if our by-laws still reference the old Corporations Act?
The October 18, 2024 transition deadline has passed. Corporations that never updated their governing documents are not dissolved or prevented from operating, but any by-law provisions that conflict with ONCA are deemed amended to conform — meaning your written by-laws may no longer accurately describe your actual legal obligations. A governance review is strongly advisable if this hasn’t been done.
Can a non-profit have fewer than 3 directors if it’s very small?
No. Three directors is the ONCA-wide statutory minimum regardless of the corporation’s size or revenue — there is no small-organization exception. The articles can require more, but never fewer.
Is the Corporations Information Act annual return the same as the CRA’s T3010?
No. The Corporations Information Act annual return is a provincial corporate-registry filing (Ontario Business Registry) required of the corporation itself. The T3010 is a separate federal filing required only of organizations that are registered charities with the CRA. Registered charities typically owe both.
