Most Ontario small business owners don't miss a filing because they don't care — they miss it because nobody wrote it down anywhere. Corporate filings, tax remittances, licence renewals, and employment obligations arrive on different schedules from different authorities, and none of them send a particularly memorable reminder. A regulatory compliance calendar is simply the practice of putting every one of those recurring dates in one place, before something slips.
This article lays out the recurring items an Ontario small business typically needs to track, organized by category, so you can build your own calendar around them.
Why a Compliance Calendar Matters
A missed corporate filing can quietly put a corporation out of good standing, which tends to surface at the worst possible moment — during a financing application, a lease renewal, or a sale, when a lender, landlord, or buyer asks for a certificate of status and it doesn't come back clean. Missed tax or payroll deadlines carry their own separate consequences. None of this requires anything dramatic to go wrong; it just requires nobody owning the calendar.
Recurring Corporate Filings and Meetings
| Item | Frequency | Notes |
|---|---|---|
| Ontario annual return (Corporations Information Act, filed via the Ontario Business Registry) | Yearly | Filing fee is $0 as of mid-2026 — verify before relying on it. Still must be filed even though there's no fee. |
| CBCA annual return (if federally incorporated) | Yearly | Carries its own filing fee when filed online, separate from any Ontario obligations — figures change, verify current amounts. |
| Annual shareholders' meeting, or a valid written resolution signed by all voting shareholders in lieu | At least once every 12–15 months | Ontario's Business Corporations Act requires the first meeting within 18 months of incorporation, and no more than 15 months after the prior one. |
| Update to directors, officers, or registered address | As changes occur, not on a fixed date | Should be reported to the registry without unreasonable delay under the Corporations Information Act — don't let this wait for the next annual return. |
| Business name renewal, if operating under a registered trade name | Every 5 years | Carries a modest registration fee as of mid-2026 — verify the current amount before relying on it. |
Recurring Tax and Payroll Obligations
- GST/HST registration and returns. Once a business is past the small-supplier revenue threshold (or registers voluntarily below it), it generally must charge and remit GST/HST on an ongoing filing schedule. Registration is required within a short window after crossing the threshold — figures and exact windows change, so verify the current rules before relying on them.
- Payroll source deductions. Remittances for income tax, CPP, and EI withheld from employees are due on their own recurring schedule, separate from GST/HST.
- Employer Health Tax (EHT). Ontario employers above a certain Ontario payroll level owe EHT, with monthly instalments required once payroll passes a higher threshold — an exemption exists for eligible employers below a lower payroll amount. These thresholds change periodically, so confirm the current figures with your accountant.
- WSIB premiums. Most employers with workers must register for WSIB coverage and report periodically based on payroll and industry classification; the construction industry has its own mandatory-coverage rules that catch some independent operators by surprise.
Employment-Related Recurring Checks
- Confirm minimum wage rates at least annually, since Ontario's minimum wage rates are periodically adjusted.
- Review termination clauses in employment contracts on a similar cycle — Ontario courts have struck down many employer termination clauses over the years on technical wording grounds, so a clause that was sound when drafted may not stay that way.
- Confirm WSIB coverage remains current as staffing changes.
- Keep required workplace postings up to date.
Records and Corporate Housekeeping
Beyond filings with a specific due date, a well-run corporation periodically reviews its minute book — articles, by-laws, minutes and resolutions, and registers of directors, officers, and shareholders. An out-of-date minute book is one of the most common problems that surfaces when a business seeks financing or goes up for sale, precisely because nobody treated it as a recurring task.
Building Your Calendar: A Practical Approach
- List every registration, filing, and licence the business holds, with its renewal or filing cycle, in one place.
- Assign an owner for each item — a specific person responsible for either filing it or confirming it's been filed.
- Set reminders well ahead of each deadline, not on the deadline itself, so there's time to gather documents or fix an issue.
- Review the calendar with your lawyer and accountant at least once a year, since obligations change as the business grows — crossing a revenue threshold, hiring your first employee, or adding a new location can all add new recurring items.
Frequently asked questions
What happens if I miss the Ontario annual return?
A corporation that falls behind on its filings generally falls out of good standing with the registry, which can complicate financing, leasing, or a sale, and in cases of prolonged non-compliance can put the corporation at risk of administrative processes. The specifics depend on how long the lapse continues — the better approach is simply not to let it happen.
Do I need a lawyer to file these, or can I do it myself?
Some items, like the Ontario annual return, can be self-filed through the Ontario Business Registry. Others — particularly anything touching share structure, shareholder agreements, or a change that affects the corporation's governance — benefit from legal review before they're filed.
Does a numbered company have different compliance obligations than a named one?
No. Whether a corporation has a numbered legal name (like "1234567 Ontario Inc.") or a distinctive one has no bearing on its filing obligations — they're identical either way.
Is a federally incorporated (CBCA) business's calendar different from an Ontario one?
Yes, in a few respects. A CBCA corporation files its own separate annual return with the federal corporate registry, and if it carries on business in Ontario, it generally also needs to register extra-provincially here — both are recurring items an Ontario-only OBCA corporation doesn't have.
