Most small business owners don’t get into trouble because they did something shady. They get into trouble because a deadline slipped by, a form never got filed, or nobody updated the corporate records after a change. It’s boring work, and it’s easy to push aside when you’re busy running the business.
But compliance problems tend to show up at the worst times: when you’re selling the company, applying for a loan, bringing on a partner, or dealing with a CRA letter. This checklist walks you through what Canadian small businesses need to stay on top of, in plain language, so nothing catches you off guard.
The Short Answer: What Does Corporate Compliance Involve?
Corporate compliance for a Canadian small business means meeting your legal obligations in five areas: annual corporate filings, up-to-date corporate records (your minute book), tax and payroll filings, licences and permits, and employment and privacy rules. Which rules apply depends on whether you incorporated federally or provincially, and on your industry and location.
Missing these can lead to late fees, loss of good standing, personal liability for directors, and in serious cases, dissolution of the corporation.
Why Compliance Matters More Than Most Owners Think
A corporation is a separate legal entity. That separation is what protects your personal assets, but it only holds up if the company is run like a real, separate entity. Courts can look past the corporate structure when records are missing, money is mixed with personal funds, or formalities are ignored.
Compliance also affects practical things:
- Good standing. Banks, lenders, landlords and government agencies may ask for proof your corporation is active and in good standing.
- Sales and investment. Buyers and investors do due diligence. Messy records slow deals down or lower the price.
- Director liability. Under laws like the Canada Business Corporations Act (CBCA), directors can be personally liable for certain unpaid amounts, such as employee wages and unremitted source deductions.
Step 1: Confirm Which Rules Apply to You
Before anything else, know where your corporation lives.
Federal corporations are incorporated under the CBCA and deal with Corporations Canada. Provincial corporations are incorporated under a provincial act (Ontario’s Business Corporations Act, for example) and file with the provincial registry.
Both types also have to follow federal tax rules, and both need to register to carry on business in each province where they operate. If you’re not sure which type you have, check your certificate of incorporation. It names the statute you were incorporated under.
This matters because deadlines, forms and fees differ. Everything below is general guidance for Canada, so check the details for your province.
Step 2: Keep Up With Annual Corporate Filings
Every corporation has to file some kind of annual update with its registry. It confirms your address, directors and officers.
- Federal (CBCA) corporations file an annual return with Corporations Canada within 60 days after the anniversary of incorporation.
- Provincial corporations file according to provincial rules. In Ontario, for example, the annual return is generally filed together with the T2 corporate tax return. Other provinces have their own separate deadlines.
Two habits help here. First, put the filing deadline in your calendar the day you incorporate. Second, file a change notice whenever directors, officers or your registered office address change. Most registries require this within a set number of days (often 15), and it’s separate from the annual return.
Skipping annual returns is one of the most common reasons corporations get flagged. Registries can and do dissolve corporations for repeated non-compliance, and reviving one is more expensive than filing on time.
Step 3: Maintain Your Minute Book
Your minute book is the official record of the corporation. Think of it as the company’s paper trail (today, usually a digital one). It should include:
- Articles of incorporation and certificate of incorporation
- By-laws
- Register of directors, officers and shareholders
- Share certificates and a securities register
- Director and shareholder resolutions and minutes
- Declarations of interest from directors, where applicable
The mistake I see most often is that owners incorporate, put the documents in a drawer, and never touch them again. Then a share gets issued informally, a director leaves, or a dividend gets paid, and none of it is documented.
Whenever something significant happens, such as issuing shares, appointing a director, paying dividends, taking on major debt or selling a big asset, there should be a resolution on file. Keep corporate records for the life of the company. Under the CBCA, records must be kept at your registered office or another place in Canada, and you should be able to produce them promptly.
Step 4: Hold Annual Meetings or Sign Written Resolutions
Corporations have to make certain decisions every year. For CBCA corporations, that includes holding an annual shareholders’ meeting (within 15 months of the last one, and no later than six months after your financial year-end), presenting the financial statements, electing directors, and dealing with the auditor question.
The good news: most small, closely held corporations don’t hold a real meeting. Instead, all shareholders sign written resolutions that cover the same business. It’s faster and just as valid, as long as it’s done properly and kept in the minute book.
On the audit question, many small non-distributing corporations can skip a formal audit if all shareholders agree in writing. That consent needs to be renewed each year, so don’t assume last year’s still applies.
Step 5: Keep Your Register of Individuals With Significant Control Current
This one is newer and often missed. Federal corporations must keep a register of individuals with significant control (ISC), which are people who own or control 25% or more of the voting shares or of the fair market value of all shares, or who have significant influence over the corporation in other ways.
Since January 2024, ISC information for federal corporations is also available through a public registry maintained by Corporations Canada, and the information is updated through the annual return. Some provinces have introduced their own beneficial ownership rules as well, so check what your province requires.
Keep the register accurate. Update it within the required timeframe when ownership changes, and take reasonable steps to confirm the information is correct.
Step 6: Stay Current on Tax Compliance
This is where the penalties add up fastest. The Canada Revenue Agency (CRA) has strict deadlines and doesn’t treat “I forgot” as a reason to waive them.
Corporate income tax (T2). Your T2 return is due six months after your fiscal year-end, even if you owe nothing. Any balance owing is due earlier: two months after year-end, or three months for many Canadian-controlled private corporations that qualify. A late T2 return generally triggers a penalty of 5% of the balance owing plus 1% for each full month late, up to 12 months.
GST/HST. You must register once your taxable revenues pass $30,000 over four consecutive calendar quarters. Your filing frequency (monthly, quarterly or annually) depends on your annual revenue. See the CRA’s GST/HST guidance for businesses for the current rules.
Payroll. If you pay employees (and that can include yourself as an owner-manager), you have to deduct CPP, EI and income tax, then remit them on time. Remittance frequency depends on your average monthly withholding. Many small employers remit by the 15th of the following month. T4 slips are due by the end of February. The CRA’s payroll pages explain the schedules.
Dividends and other slips. If you pay dividends, you’ll generally need to issue T5 slips, also due at the end of February.
Directors can be personally liable for unremitted payroll deductions and GST/HST, so treat these as priorities and not something to catch up on later.
Step 7: Watch Shareholder and Director Loans
Owners often move money in and out of their company informally. It works day to day, but it can create tax problems. In general, if a shareholder borrows money from the corporation and doesn’t repay it within one year after the end of the corporation’s tax year in which the loan was made, the amount may have to be included in that shareholder’s personal income.
Keep a shareholder loan account, document every transaction, and talk to your accountant before year-end about any balance owing either direction. Clean records here save a lot of trouble later.
Step 8: Check Licences, Permits and Industry Rules
Incorporating doesn’t give you the right to operate. Depending on what you do and where, you may need:
- A municipal business licence
- Provincial or professional licences (for example, in construction, food service, transportation, or financial services)
- Registration in each province where you carry on business
- Workers’ compensation coverage, where required
- Zoning and health approvals
Renewals are easy to lose track of, especially when different licences expire on different dates. Keep a single list with every licence, its issuing body, its renewal date and its fee.
Step 9: Cover Employment, Privacy and Marketing Rules
If you have staff, employment standards law in your province sets rules on minimum wage, hours, overtime, vacation pay, statutory holidays, termination and record keeping. Written employment agreements and clear workplace policies help both sides know where they stand.
If you collect personal information from customers or employees, privacy law likely applies to you. Federally, PIPEDA governs how private-sector organizations handle personal information in the course of commercial activity, and some provinces have their own laws. At minimum, know what you collect, why you collect it, where you store it, and how you’d respond to a breach.
If you send marketing emails or texts, Canada’s anti-spam law (CASL) requires consent and a working unsubscribe option. The CRTC explains the rules on its CASL page.
Step 10: Keep Your Records Long Enough
The CRA generally expects you to keep tax records and supporting documents for six years from the end of the last tax year they relate to. That includes invoices, receipts, bank statements, payroll records and general ledgers.
Corporate records like your minute book should be kept for the life of the corporation. Store digital copies in a secure, backed-up location, and make sure at least one other trusted person knows where everything is.
A Simple Yearly Compliance Calendar
Here’s a rough rhythm you can adapt. Confirm exact dates for your corporation and province.
Right after year-end
- Close the books and get financial statements prepared
- Review shareholder loan balances
- Pay any corporate tax balance owing
Within a few months of year-end
- Sign annual shareholder and director resolutions
- File your T2 return (due six months after year-end)
- File your annual return with the correct registry
- Update the ISC register and other registers
Throughout the year
- Remit payroll deductions on schedule
- File GST/HST returns on your assigned frequency
- Record resolutions when major decisions are made
- File change notices when directors, officers or addresses change
End of January and February
- Issue T4 and T5 slips (due end of February)
Once a year
- Renew licences and permits
- Review insurance coverage
- Review your by-laws and shareholder agreement to see if they still fit
Common Compliance Mistakes to Avoid
Treating the corporation like a personal bank account. Mixing personal and business spending weakens your liability protection and creates tax problems.
Not updating records after changes. A director resigns, a shareholder sells, an address changes, and the registers never get updated.
Ignoring small filings. A nil return or a routine annual return still has to be filed.
Relying on old templates. By-laws and shareholder agreements drafted years ago may not reflect how the business works now, or current law.
Assuming the accountant handles everything. Accountants handle tax and financial statements. Corporate law filings, minute book updates and resolutions often fall in a gap, so confirm who is responsible for each item.
Waiting until there’s a problem. Fixing years of missed filings costs far more than staying on top of them.
When Should You Get a Lawyer Involved?
You don’t need a lawyer for every filing, but a few situations are worth the call:
- You’re behind on filings or your corporation has been dissolved or is at risk of it
- You’re adding or removing a shareholder, or bringing in an investor
- You’re buying, selling or restructuring the business
- You’ve found gaps in your minute book and need them cleaned up
- You’re setting up or updating a shareholder agreement
- You’ve received a notice from a registry or the CRA

Final Thoughts
Corporate compliance isn’t glamorous, but it’s one of the cheapest forms of protection a small business has. Know your deadlines, keep your records current, and separate personal and business finances. Do those three things consistently and you’ll avoid most of the problems that trip up small corporations.
Use the checklist above as a starting point, adjust it for your province and industry, and review it once a year.
