You have registered the company, picked a name, lined up your first customers, and you are moving fast. That momentum is exactly when the unglamorous legal foundations tend to get skipped, and most business mistakes Canadian companies make are not dramatic. They are small omissions: a name that was never cleared, a co-founder arrangement that was never written down, a contractor whose work the company does not actually own. None of them feel urgent in month one. All of them get more expensive to fix as the business grows. Here are ten common ones, and the practical steps that head them off.
1. Treating incorporation as an afterthought
Incorporation is the step that separates your personal assets from the business, and waiting too long to take it is a common early mistake. A sole proprietorship is simple to start, but the owner is personally responsible for the business's debts and liabilities. A corporation is a separate legal person, so in most cases its obligations stay with the corporation rather than its shareholders. That separation, often called limited liability, is a common reason founders incorporate before signing significant contracts or taking on customers.
The second half of this mistake is incorporating in the wrong place without thinking it through. You can incorporate federally under the Canada Business Corporations Act or provincially, for example under Ontario's Business Corporations Act. The choice affects name protection, filing obligations, and cost. The table below sets out the main differences for a business deciding between federal and Ontario incorporation.
| Factor | Federal (CBCA) | Ontario (OBCA) |
|---|---|---|
| Government filing fee | About $200 online, as of June 2026 (Corporations Canada) | $300 online, as of June 2026 (ServiceOntario) |
| Name protection | Name reviewed for confusion Canada-wide | Name not assessed against names in other provinces |
| Annual return | Filed with Corporations Canada, about $12 online | Filed through the Ontario Business Registry, no fee |
| Extra-provincial registration | May still need to register in provinces where you operate | Registered in Ontario; other provinces may require registration |
Neither option is automatically right. A business planning to operate across several provinces may prefer the broader name protection of federal incorporation, while a company focused on Ontario may find provincial incorporation simpler.

2. Assuming a registered business name protects the brand
A registered business name and a trademark are not the same thing, and confusing them is a frequent branding mistake. Registering a business name, or incorporating under a corporate name, records that you operate under that name. It does not, on its own, grant the exclusive right to use the name as a brand. A trademark registration is what gives the exclusive right to use a name in connection with specific goods and services across Canada.
The practical consequence is that clearing a name to incorporate tells you little about whether you can safely build a brand around it. Another business may already hold trademark rights in a similar name, including rights built up through use rather than registration, because unregistered marks can acquire enforceable rights in Canada. Treating the corporate-registry search as the end of the name question, rather than the beginning, is where this mistake usually starts. The post on how to trademark a name in Canada explains the distinction in more detail.
3. Building a brand before running a clearance search
A clearance search before you commit to a name is one of the cheapest forms of risk management available, and skipping it is a costly habit. Once a company has printed packaging, built a website, and earned recognition under a name, discovering that the name conflicts with someone else's trademark can mean rebranding. Rebranding involves new signage, packaging, domain names, and marketing materials, which is far more expensive than checking availability at the outset.
A proper clearance search looks beyond identical names to confusingly similar marks, and beyond the trademark register to common-law use. A quick search of the CIPO trademarks database is a useful first step, but it has limits, and it does not surface unregistered marks or assess how close is too close. Clearview offers professional clearance searches as part of its trademark packages, and the post on Canadian trademark searches covers what a thorough search involves.
4. Co-founding without a shareholder agreement
If a corporation has more than one shareholder, the absence of a shareholder agreement is a gap that tends to surface at the worst possible time. A shareholder agreement is a private contract among the shareholders that sets out how decisions are made, what happens if a founder wants to leave, dies, or becomes unable to work, and how shares can be transferred or valued. Without one, the corporation falls back on the default rules in the governing corporate statute, which may not reflect what the founders actually intended.
The reason this can be a mistake rather than a deferral is timing. The agreement is often easiest to negotiate at or near incorporation, while the founders' interests are aligned. Waiting until a disagreement arises can make the same conversation much harder, however, if everyone's expectations aren't already clearly defined. The post on why every corporation needs a shareholder agreement walks through the clauses these agreements typically cover.
5. Not securing intellectual property ownership in writing
Many founders assume that paying for work means owning it. Under Canadian copyright law, that assumption can be wrong. An independent contractor generally retains copyright in what they create unless they assign it in writing, which means a company can pay a developer for software or a designer for a logo and still not own the result without a signed assignment. For work created by employees in the course of employment, the employer is often the first owner of copyright, but the line between an employee and a contractor is not always clear, which is its own risk (see mistake 7).
The fix is straightforward and inexpensive: include written intellectual property assignment language in every contractor, freelancer, and employee agreement, signed before the work begins. This matters most for the assets a business is built on, such as source code, brand designs, and content. Clearview can advise on intellectual property protection for software companies and the assignment terms that keep ownership with the company.
6. Operating on handshakes and generic templates
Doing business without written contracts, or relying on a template pulled from the internet, is a mistake that stays invisible until something goes wrong. A handshake deal can work until a customer disputes scope, a supplier misses a deadline, or a partner remembers the terms differently. At that point, the absence of a clear written agreement leaves everyone arguing about what was promised, often with no good record to rely on.
Generic templates carry a related risk. A template drafted for another jurisdiction, particularly a United States template, may use concepts that do not have the intended effect in Canada, or may leave out protections a Canadian business needs. Templates also skip the useful step of the parties actually agreeing on the hard questions before signing. Written agreements that fit the deal, even short ones, are generally worth the modest investment. The post on what a contract review lawyer looks for covers the terms that most often matter.
7. Misclassifying employees as independent contractors
Labelling a worker an "independent contractor" does not make them one. In Ontario, the Employment Standards Act, 2000 and the Canada Revenue Agency look at the true nature of the relationship, not the title on the contract. Factors that courts, the CRA, and the Ministry of Labour weigh include the degree of control over the work, who supplies the tools, the worker's opportunity for profit and risk of loss, and how integrated the worker is into the business.
Getting this wrong can be expensive. If a worker treated as a contractor is later found to be an employee, the business can face liability for unpaid source deductions, employment standards entitlements such as vacation and termination pay, and related penalties. The risk grows as a company relies on long-term, full-time "contractors" who function like staff. A written agreement helps, but only if the working relationship actually matches it.
8. Writing non-compete clauses into employee contracts in Ontario
Importing a non-compete clause into an Ontario employment contract is a mistake that often reflects out-of-date or out-of-jurisdiction assumptions. Since October 25, 2021, section 67.2 of Ontario's Employment Standards Act, 2000, added by the Working for Workers Act, 2021, prohibits employers from entering into non-compete agreements with employees, and a clause that breaches the prohibition is void. Limited exceptions apply, including certain executives and non-competes tied to the sale of a business where the seller becomes an employee of the buyer.
This is an area where United States practice does not translate. The familiar idea that a reasonable non-compete will be enforced does not reflect the current Ontario rule for most employees. Businesses that want to protect customer relationships and confidential information generally do better with non-solicitation and confidentiality clauses, which are treated differently and remain available. The post on when your business needs a contract lawyer explains where these tools fit.
9. Treating privacy and anti-spam law as someone else's problem
Privacy and anti-spam obligations apply to far more businesses than founders expect, and ignoring them until a complaint arrives is a common mistake. The Personal Information Protection and Electronic Documents Act (PIPEDA) applies to organizations that collect, use, or disclose personal information in the course of commercial activity across most of Canada. Among other things, PIPEDA requires organizations to report breaches of security safeguards that pose a real risk of significant harm to the Office of the Privacy Commissioner of Canada, to notify affected individuals, and to keep records of all such breaches for 24 months (as of June 2026).
Canada's Anti-Spam Legislation (CASL) adds a separate layer for businesses that send commercial electronic messages, such as marketing emails. A new company that builds an email list or launches a product without a privacy policy, consent practices, and a basic breach-response plan is taking on avoidable risk. The post on privacy by design explains how to build these obligations in from the start rather than bolting them on later.
10. Letting corporate housekeeping slide
Once the excitement of incorporating passes, ongoing compliance is easy to forget, and falling behind is one of the more avoidable mistakes on this list. Corporate housekeeping includes several recurring obligations:
- Annual returns. Federal corporations file an annual return with Corporations Canada within 60 days of their anniversary date (about $12 online, as of June 2026). Ontario corporations file an annual return through the Ontario Business Registry, which currently carries no fee.
- The minute book. Corporations are expected to keep records current, including directors and officers, share issuances, and resolutions. A neglected minute book often surfaces as a problem during a financing or a sale, when a buyer's lawyer asks to review it.
- Transparency registers. Federal corporations must maintain a register of individuals with significant control, and Ontario corporations have a comparable obligation. These are ongoing record-keeping duties, not one-time tasks.
- GST/HST registration. A business generally must register for GST/HST with the CRA once its worldwide taxable revenue exceeds $30,000 in a single calendar quarter or over four consecutive quarters (as of June 2026).
None of these are difficult on their own. The mistake is letting them accumulate, because catching up later is more work than staying current. The post on annual corporate maintenance for Ontario companies sets out a practical checklist.
A note on scope
Clearview advises Ontario businesses on corporate, contract, employment, and privacy matters, and works with clients across Canada and internationally on trademark and other intellectual property matters. Several of the rules above, such as the non-compete prohibition and provincial incorporation, are specific to Ontario; if your business operates elsewhere, the provincial details will differ, and you should confirm the rules that apply where you are. Federal rules, including PIPEDA, CASL, federal incorporation, and GST/HST, apply more broadly.
Getting the foundations right
The common thread across these ten mistakes is that each is cheaper to prevent than to repair. A clearance search costs less than a rebrand. A shareholder agreement signed at incorporation costs less than a founder dispute. An intellectual property assignment signed before work begins costs less than litigating who owns the code. Building the legal foundations early does not slow a business down; it removes the friction that surfaces later.
