Ontario Notice of Change For Corporations

Most Ontario Notice of Change filings are processed the same business day. Once you approve the draft, Ontario Business Central submits the filing electronically to the Ontario Business Registry and the changes go live instantly. You receive an email confirmation as soon as the corporate record is updated.

The cost is $45.10 service fee plus $55.00 data extract fee and $55.00 draft fee, for a subtotal of $155.10. With $20.16 HST, the total is $175.26. The Ontario government does not currently charge a filing fee for a Notice of Change. Multiple changes can be filed together for the same fee.

A Notice of Change is used to update your corporate address, director addresses, the addition or removal of directors, officer positions, business activity (NAICS code), and the corporation's email address. To change the corporation's name, share structure, or minimum or maximum number of directors, you must file Articles of Amendment instead.

A Notice of Change updates information that sits outside your Articles of Incorporation, such as directors, officers, addresses, and business activity. Articles of Amendment are required when changing the actual incorporating document, such as the corporation's name, share structure, or minimum or maximum number of directors. Notice of Change filings are processed same business day; Articles of Amendment require a more involved filing process and higher government fees.

The Company Key is a 9-digit security code introduced October 19, 2021 with the launch of the Ontario Business Registry. It acts like a password and is mandatory to authorize any changes to a corporation's record. Without a Company Key, the Ontario Business Registry will not process the Notice of Change. Ontario Business Central can retrieve your Company Key on your behalf if you do not have it.

No. Since October 19, 2021, the Ontario Business Registry requires a valid Company Key to process any change to a corporation's record. You can place your order with Ontario Business Central without the Company Key, but the filing cannot be submitted until the key is retrieved. We offer a Company Key retrieval service so the Notice of Change can move forward without delay.

No. A Notice of Change is filed only when there is an actual change to your directors, officers, addresses, or business activity, and must be filed within 15 days of the change occurring. The annual filing required for every active Ontario corporation is the Ontario Annual Return, which is a separate filing that confirms the corporate record is current.

Failing to file a Notice of Change within 15 days places the corporation out of compliance with the Ontario Business Corporations Act. The public corporate record will continue to show outdated director or officer information, which can create legal exposure for departed directors who are still listed, complicate banking and contracts, and lead to penalties or refusal of other corporate filings. Updating the record promptly protects both the corporation and its officers.

The previous corporate record is preserved within the Ontario Business Registry as part of the corporation's filing history. The Notice of Change does not erase prior information; it adds an updated record that becomes the current snapshot of the corporation. A Corporate Profile Report can be ordered at any time to show the full filing history alongside the current record.

Yes. A Notice of Change is an official filing made under the Ontario Business Corporations Act. Once accepted by the Ontario Business Registry, the updated information becomes part of the corporation's official public record and is accepted by banks, courts, and government agencies as proof of the change. A Corporate Profile Report can be ordered alongside the filing as additional documented proof of the update.

Yes. Multiple updates can be combined into a single Notice of Change filing for the same fee. For example, you can change the corporate address, add a new director, and update an officer position all in one filing. This is one of the most cost-effective ways to keep your Ontario corporation current with the Province.
