10 Legal Mistakes Ontario Small Businesses Must Avoid

1. Treating Limited Liability A Ab olute

Incorporating create a eparate legal entity, and that eparation i real. But mall bu ine owner routinely overe timate how much protection it give them, becau e the two large t exception are the one they encounter fir t.

Per onal guarantee . Your bank will want one on the operating line. Your landlord will want one on the commercial lea e. Your major upplier may want one on trade credit. Each ignature move that liability back onto you per onally, and a guarantee on a five-year lea e can outlive the bu ine by year . Small bu ine owner often ign everal of the e in their fir t eighteen month without regi tering that they have undone the thing they incorporated for.

Director liability. Director of an Ontario corporation can be held per onally liable for pecific obligation regardle of the corporate tructure, including unpaid employee wage and vacation pay, unremitted payroll ource deduction , and unremitted HST. The e are not theoretical, they are among the mo t common way a director end up per onally expo ed when a bu ine fail .

Two practical con equence . Fir t, read guarantee a per onal document , not corporate one , and negotiate their cope and duration. Second, if the bu ine i under financial pre ure, ource deduction and HST are the la t thing to fall behind on, not the fir t.

Setting a ide the e exception , Canadian court are reluctant to look behind the corporate tructure and hold hareholder liable for corporate debt . The thre hold i high and the circum tance narrow. The reali tic ri k to your per onal a et come from what you ign and from the pecific tatutory liabilitie above, not from imperfect record-keeping.

2. Choo ing A Structure By Default Rather Than Deliberately

A ole proprietor hip i you, carrying on bu ine . There i no eparate entity, o bu ine debt and claim are your debt and claim .

A corporation i a eparate legal per on that own it own a et , ign it own contract , and carrie it own liabilitie , ubject to the exception above.

“Incorporating will reduce my taxe .” Not automatically. A corporation earning active bu ine income in Ontario may acce a lower rate on income below a et thre hold, which create a genuine deferral advantage if profit are left in the company. If you draw everything out to live on, much of that advantage di appear . And corporate lo e are trapped in the corporation , an early- tage bu ine lo ing money often doe better unincorporated, where lo e can off et other per onal income. Thi i an accounting que tion a much a a legal one. Run the number with your accountant before incorporating for tax rea on .

“I have to have a Canadian re ident director.” Ontario removed it director re idency requirement in 2021. Older guide till repeat it.

The tructure que tion al o depend on whether you will bring in inve tor , whether you want to ell the bu ine eventually, and what your liability profile actually look like. A con ulting bu ine with no employee and no premi e i in a different po ition from a contractor with a crew and a yard.

3. Calling People “Partner ” Without Meaning It

Thi one i genuinely dangerou and almo t never intentional.

In Ontario, a partner hip can come into exi tence without any document being igned. Two or more people carrying on a bu ine in common with a view to profit are a partner hip, whatever they call them elve . And partner are generally jointly liable for the obligation of the firm, which mean your bu ine a ociate’ commitment can become your per onal debt .

If you have incorporated, your co-owner are hareholder , not partner . If you have not incorporated and you are working with omeone on a hared venture with hared profit , you may already be in a partner hip you never agreed to. Either clarify the relation hip in writing or incorporate.

The habit of u ing “partner” loo ely in email , pitch deck and LinkedIn bio i worth breaking. In a di pute, that language become evidence.

4. Operating Without A Shareholder Agreement

Incorporation document ay who own the hare . They ay almo t nothing about what happen when the owner di agree.

A hareholder agreement i a contract among the hareholder governing how the company i run and how owner hip can change. Without one, a 50/50 company where the owner top agreeing ha no mechani m to break the deadlock hort of a court application, an expen ive and de tructive way to re olve a bu ine di agreement.

At minimum, an agreement hould addre what happen when a hareholder want out, die , become di abled, get divorced, or imply top contributing; how hare are valued; who can buy them and on what term ; what deci ion need unanimou approval; and how di pute are re olved. A unanimou hareholder agreement goe further, tran ferring ome or all of the director ’ power to the hareholder with corre ponding liability.

The be t time to ign one i when everyone till like each other. Every hareholder agreement negotiated during a di pute co t everal time what it would have co t at the out et, and produce a wor e re ult.

Have co-owner and no agreement? That i the mo t common and mo t expen ive gap we ee in Ontario mall bu ine e . H&H Law Group can be reached at 416-572-7483.

5. U ing Contract That Do Not Reflect The Actual Deal

Downloaded template fail in predictable way . They are u ually drafted under another juri diction’ law, they are neutral where your deal i not, and they omit the term pecific to your bu ine .

For mo t Ontario mall bu ine e the term that matter are unglamorou : payment term and what happen on late payment, a clear de cription of cope and what i excluded, who own the intellectual property created under the contract, limitation of liability, confidentiality, termination right , and the governing law and di pute re olution mechani m.

The intellectual property point de erve empha i . In the ab ence of a written a ignment, an independent contractor who develop oftware, de ign , or written material for you may own the copyright in it, not you. Bu ine e di cover thi during due diligence on a ale, which i the wor t po ible moment.

A ingle well-drafted template for your recurring tran action type, prepared once for your actual bu ine , u ually co t le than one di pute and i reu able indefinitely.

6. Employment Agreement With Termination Clau e That Do Not Hold Up

Thi i the ingle mo t expen ive employment mi take Ontario mall employer make.

The Employment Standard Act, 2000 et minimum notice and everance entitlement . It i a floor, not a ceiling. In the ab ence of an enforceable contractual term limiting an employee to tho e minimum , the employee i entitled to common law rea onable notice, which for a long- ervice or enior employee can run to many month of compen ation, far beyond the tatutory minimum.

The trap i that Ontario court have repeatedly truck down termination clau e that fall hort of the ESA in any re pect, and a defect in one part of the termination language can invalidate the whole provi ion, including part the employer never relied on. When that happen , the limit di appear and common law notice applie .

Ontario ca e law in thi area i active and ha continued to move through 2025 and 2026. A termination clau e drafted five year ago may no longer be enforceable, and a clau e that wa vulnerable la t year may be fine now. The practical in truction i imple: have your employment agreement template reviewed again t current law, and review it periodically rather than once.

Separately, everal Ontario obligation , written policie on electronic monitoring and di connecting from work, and the job po ting rule that took effect at the tart of 2026 apply only to employer at or above a 25-employee thre hold. Mo t mall bu ine e it below it, but bu ine e that grow acro that line often do not notice when they cro it.

7. Calling An Employee A Contractor

Label do not determine the relation hip. Court , the Mini try of Labour and the Canada Revenue Agency all look at the ub tance: who control how and when the work i done, who provide the tool , whether the worker can profit or lo e from their own management of the work, and how integrated the worker i into the bu ine .

The con equence of getting it wrong run in everal direction at once:

A written contractor agreement help but doe not decide the que tion. If the working relation hip look like employment, the agreement will not ave it. Structure the relation hip fir t, then paper it.

• CRA can a e unremitted ource deduction , CPP and EI contribution retroactively, with intere t and penaltie , again t the bu ine .
• The ESA prohibit mi cla ification and place the onu on the employer to prove the worker i not an employee. Back entitlement to overtime, vacation and public holiday pay can follow.
• Court recogni e an intermediate category, the dependent contractor, who work primarily for one client and i entitled to rea onable notice on termination de pite not being an employee.

8. A uming A Regi tered Bu ine Name Protect Your Brand

The e are three different thing and they do different work:

A NUANS earch run at incorporation i not a trademark earch. It will not tell you whether your name infringe an exi ting regi tered mark, which i how bu ine e end up rebranding after two year of building recognition.

Copyright in original work ari e automatically, but owner hip default matter: work created by an employee in the cour e of employment generally belong to the employer; work created by a contractor generally doe not, ab ent a written a ignment. See point 5.

• Regi tering a bu ine name in Ontario record that you are operating under that name. It confer no exclu ive right what oever. Someone el e can regi ter the ame name.
• Incorporating under a name give you that corporate name, but it i not a trademark and doe not top other from u ing a imilar name in the market.
• A regi tered trademark under the federal Trademark Act give exclu ive right acro Canada for the good and ervice it cover . It i the only one of the three that actually protect a brand.

9. Letting Corporate Hou ekeeping Slide

Annual return . Ontario corporation mu t file an annual return with the province. The filing proce changed with the introduction of the Ontario Bu ine Regi try, and a number of corporation quietly fell out of compliance when the old route through the CRA clo ed. Per i tent failure to file can lead to a corporation being cancelled which i di covered at the wor t po ible time, typically when trying to clo e a financing or a ale.

The minute book. Share certificate , director ’ re olution , hareholder regi ter and annual approval feel like paperwork until omeone doe due diligence on your bu ine . A di organi ed or incomplete minute book delay tran action , reduce buyer confidence, and ometime co t real money in purcha e price adju tment or holdback . Recon tructing a decade of mi ing record i far more expen ive than maintaining them.

Neither of the e i urgent in any given month, which i exactly why they get deferred for year .

10. Mixing Per onal And Bu ine Finance

Running per onal expen e through the corporation and bu ine expen e through a per onal account create problem that are financial and tax-related rather than liability-related.

Withdrawal that are not properly characteri ed a alary, dividend or a repayment of capital may be treated a hareholder loan , which carry their own tax rule and, if not repaid within the required period, can be included in your per onal income. Per onal expen e claimed a bu ine deduction are a tandard CRA audit finding. And a bu ine who e book cannot cleanly di tingui h per onal from corporate pending i difficult to value, difficult to finance, and difficult to ell.

Separate account , a clear policy on owner compen ation, and an accountant who ee the account regularly re olve mo t of thi .

The One That Make All The Other Wor e

Calling a lawyer only once a di pute exi t . By that point the option are con trained by deci ion already made, a guarantee already igned, a contract already performed, an employee already terminated, a hareholder already deadlocked.

The preventive ver ion of everything above are mode t, one-time co t . The reactive ver ion are open-ended.
