How to file an annual return in Ontario
Ontario's annual return regime is unusual: it does not require a standalone Annual Return like the CBCA. Ontario information updates are filed through the corporate tax return (Corporations Information Act s. 3) and through the Business Registry. The Transparency Register under OBCA s. 140.2, added January 1, 2023, is a separate ongoing obligation. The Corporations Information Act since 2021 has consolidated filings through the Business Registry.

Ontario's no-direct-annual-return regime
Ontario is unusual among Canadian provinces in not requiring a standalone Annual Return. The corporation's annual information obligation is satisfied by including required information in the corporate tax return (CT23) filed with the Ministry of Finance. The Corporations Information Act, amended in 2021 to consolidate Ontario corporate filings through the new Business Registry, removed several filing redundancies.
The Transparency Register since January 2023
OBCA s. 140.2, effective January 1, 2023, requires every Ontario corporation to maintain a Transparency Register of individuals with significant control (25%+ voting shares or otherwise exercising control). The register is filed with the Ministry of Public and Business Service Delivery through the Business Registry. The Transparency Register is not the same as the federal CBCA ISC register; Ontario corporations have separate Ontario provincial obligations even if they coordinate with federal beneficial-ownership reporting.
The Business Registry consolidation
Ontario consolidated corporate filings into a single Business Registry in October 2021, replacing several legacy filing systems. The Registry handles articles amendments, director changes, registered-office changes, and transparency-register updates. Information that was previously updated through the Annual Information Return is now updated as it changes through the Registry.
Administrative dissolution under s. 240
Under OBCA s. 240, the Director (Ministry of Government and Consumer Services) may administratively dissolve a corporation that has been delinquent in its filings (typically 2 consecutive years of non-filing). Notice is given to the registered office. Reinstatement under s. 241 is possible by filing all missed information and paying reinstatement fees.
Coordination with the Ontario corporate tax return
Most Ontario annual-information obligations are satisfied through the CT23 corporate tax return filed with the Ministry of Finance within 6 months of fiscal year-end. The CT23 includes director changes, registered-office address, and other information that other provinces require in a separate annual return. This consolidation reflects Ontario's emphasis on filing efficiency.
Procedure
The annual-return procedure as it applies in Ontario, in seven steps:
Confirm current directors against the minute book
Ontario tracks director changes through the Business Registry. Confirm that the directors named in the Registry match the directors actually serving per the minute book. Director changes should be filed within 15 days of the change under OBCA s. 113.Update the Transparency Register
Under OBCA s. 140.2, the Transparency Register lists individuals with significant control. Update at every change of significant-control ownership, and confirm currency at least annually.File the CT23 corporate tax return
File the Ontario corporate tax return (CT23) with the Ministry of Finance within 6 months of fiscal year-end. The CT23 includes corporate information that satisfies the Corporations Information Act obligation.File any standalone updates through the Business Registry
For changes that occur outside the tax-return cycle (e.g., a registered-office change in mid-year), file through the Business Registry at ontario.ca/page/ServiceOntario at the time of the change.Confirm registered office address
The registered office must be in Ontario at the address specified in the most recent filings. Confirm currency.File transparency-register updates within statutory windows
OBCA s. 140.2 requires the Transparency Register to be kept current. Updates are filed within 15 days of becoming aware of any change.Place all filings in the minute book
The CT23 filing acknowledgment, any Business Registry update receipts, and the current Transparency Register are placed in the minute book under the year's annual filings.
Common mistakes
Ontario's consolidated regime is efficient but confusing for corporations used to standalone annual returns. Common errors:
- Looking for a standalone Annual Return form (like CBCA's Form 22). Ontario no longer has one; annual information is in the CT23 and the Business Registry.
- Failing to maintain or update the Transparency Register under OBCA s. 140.2; the obligation is ongoing and is a separate filing channel from the corporate tax return.
- Conflating Ontario corporations and federal CBCA corporations; the two have different obligations even when the directors and shareholders are the same.
- Missing the CT23 filing window (6 months from fiscal year-end); the late filing produces tax-side penalties and corporate-information delays.
Octelligence tracks the OBCA annual-return deadline against the corporation's anniversary date or fiscal year-end, surfaces the directors, registered office, and beneficial-ownership information for the filing, and stores the filed return alongside the minute book. The jurisdiction-specific form, fee, and late-penalty rules are built in, with multi-jurisdiction portfolio views for corporations registered in more than one place.
