  • Ontario's nonprofit sector operated under the Ontario Corporations Act for decades.
  • When ONCA took effect, existing Ontario nonprofit corporations were deemed to be continued under the new Act.
  • Articles of Incorporation (Letters Patent) Under the OCA, nonprofits received letters patent rather than articles of incorporation.

If your Ontario nonprofit was incorporated under the old Ontario Corporations Act (OCA), the law governing your organization has already changed. ONCA transition compliance for Ontario nonprofits is not optional — the Ontario Not-for-Profit Corporations Act, 2010 (ONCA) came into force on October 19, 2021, and every Ontario nonprofit corporation is now subject to it, whether your documents have caught up or not.

The good news is that your corporation did not dissolve or disappear when the new law took effect. The less comfortable news is that your founding documents almost certainly contain provisions that conflict with ONCA — and those conflicts can create real governance risk. This article explains what changed, what you need to review, and what the practical steps look like.

Background: From the OCA to ONCA

Ontario's nonprofit sector operated under the Ontario Corporations Act for decades. That statute was widely criticized as outdated, designed primarily for business corporations and retrofitted for nonprofits. The Ontario Not-for-Profit Corporations Act, 2010 was passed to fix that — but its proclaimed-in-force date was repeatedly delayed.

ONCA finally came into force on October 19, 2021. On that date, every Ontario nonprofit corporation incorporated or continued under the OCA became subject to the new Act. The legislature built in a transition mechanism so organizations would not immediately be in breach of their own documents.

What "Deemed Continuance" Means

When ONCA took effect, existing Ontario nonprofit corporations were deemed to be continued under the new Act. In plain language: your corporation automatically became an ONCA corporation on October 19, 2021. You did not need to file anything for that to happen.

However, deemed continuance is not the same as deemed compliance. Your letters patent, supplementary letters patent, and bylaws were written under OCA rules. ONCA has different rules — some mandatory, some default. A provision in your existing documents that is now prohibited under ONCA is void. A matter your documents are silent on will be governed by ONCA's default rules, which may not match what your founders intended.

This is why governance review matters even though your corporation technically continued automatically.

What Needs to Be Reviewed and Updated

Articles of Incorporation (Letters Patent)

Under the OCA, nonprofits received letters patent rather than articles of incorporation. ONCA uses articles. As of writing, ServiceOntario's process requires organizations to file articles of amendment (or in some cases articles of continuance) to bring their foundational documents into line with ONCA — verify the current form and fee with ServiceOntario before filing.

Key things to check in your founding documents:

Bylaws

Bylaws are where most organizations will find the most work. ONCA sets default rules for a long list of matters — quorum, notice periods, voting thresholds, director terms — but many of those defaults can be changed by bylaw. The problem is that your existing bylaws may:

A bylaw review should go line by line against ONCA's requirements. Common fixes include updating notice provisions for member meetings, revising quorum rules, confirming electronic meeting authority, and removing OCA-era language about letters patent.

Minute Book

Your minute book should reflect the transition. Boards should pass a resolution acknowledging ONCA continuance, and any subsequent bylaw amendments need to be properly minuted and confirmed by the membership as required under ONCA.

New Concepts Under ONCA

Several concepts in ONCA have no direct equivalent under the old Act:

Public benefit vs. mutual benefit. ONCA formally classifies nonprofits as either public benefit corporations (serving a broader community — charities, community organizations) or mutual benefit corporations (serving their own members — clubs, professional associations). The classification affects rules on returning assets on dissolution and certain governance requirements.

Membership class rights. ONCA provides a more structured framework for creating multiple classes of members with different voting rights and entitlements. If you want more sophisticated membership structures, ONCA gives you clearer tools — but your existing documents need to reflect them properly.

Director liability changes. ONCA includes specific provisions on director indemnification and the due-diligence defence. Directors should be aware of what protection is available and ensure the organization's bylaws and any indemnification agreements are ONCA-compliant.

How to Update Your Articles

To formally amend your articles under ONCA, the process generally involves:

  1. Board resolution approving the proposed articles of amendment;
  2. Member approval by special resolution (at least two-thirds of votes cast at a duly called meeting, unless your articles require a higher threshold);
  3. Filing articles of amendment with ServiceOntario and paying the applicable fee (verify the current fee directly with ServiceOntario — as of writing, fees are posted on Ontario's government website).

The filed articles replace the relevant provisions of your letters patent.

Adopting ONCA-Compliant Bylaws

Updating bylaws is a two-step process under ONCA:

  1. Board resolution — the board passes the new bylaw or bylaw amendment;
  2. Member confirmation — the bylaw must be submitted to members at the next member meeting for confirmation by ordinary resolution (majority of votes cast), unless ONCA or your articles require a higher threshold.

A bylaw that is passed by the board but not confirmed by members within the required window ceases to be effective.

What Happens If You Do Nothing

Your corporation is still governed by ONCA regardless. But operating with unconformed documents creates real risk:

There is no fine for having unconformed documents, but the governance exposure is real and grows over time.

A Note for Registered Charities

If your nonprofit is also a registered charity with the CRA, your ONCA compliance obligations are separate from your charitable status obligations. The CRA has its own requirements around purposes, directors, and annual filings. ONCA compliance does not automatically satisfy CRA requirements, and vice versa. Both sets of obligations need attention.
