Starting a business is an exciting journey filled with opportunity, innovation, and growth. But before you launch your product or service into the world, it’s essential to understand the legal and structural foundations that will support your success. This guide is designed to help aspiring entrepreneurs and small business owners in Canada navigate the key considerations when starting a business, from choosing the right business structure to understanding legal responsibilities and protecting your interests.
While this guide provides valuable information, it is not a substitute for professional legal or financial advice. Be sure to consult with a lawyer and an accountant to make informed decisions tailored to your unique business goals.
Business Structures in Canada
There are three main structures:
- Sole Proprietorship
- Partnership
- Corporation
*Consult a lawyer and accountant before choosing a business structure.
Sole Proprietorship
What is it?
In a sole proprietorship, you are the sole owner. This is the most common structure for small and medium sized businesses.
- All profits (after taxes) are yours to keep
- You are fully responsible for all debts and obligations
- Creditors can make a claim against your business and personal assets
Advantages
- Simple to start
- Less administrative requirement
- Only one tax return for business and personal
- Lower taxes for net income amounts less than $90K
Disdvantages
- Unlimited liability
- Possibly higher taxes for net income over $90K
- No separation between you and your business
- May restrict access to government and other types of funding
When to use it?
Many businesses start as sole proprietorships and incorporate if and when it becomes appropriate.
- Tend to be more service-based businesses where the service provider is a self-employed professional, such as: lawyer, dentist, consultant, tattoo artist, life coach, etc.
- Liability insurance can protect you from service-related lawsuits
Partnership
What is it?
A partnership is a non-incorporated business created by two or more people.

- Financially responsible for business decisions made by partner(s)
When to use it?
Partnerships are similar to sole proprietorship.

- Liability insurance can protect you from service-related lawsuits.
Corporation
What is it?
An incorporated business issues shares to owners proportional to the percentage of ownership.

Naming Your Business
Sole Proprietorship/Partnership
Register your business name under the Business Names Act (Ontario) to receive a Master Business Licence. If the business is being carried out under the owner ’s / s’ personal name, it is not necessary to register. If it is under a different name, you must register.
Corporation
You must file articles of incorporation, provincially or federally, and then register your name. A NUANS search is required to prove that the name is not already being used.
A NUANS search compares proposed corporate names, business names and trademarks, with existing names and trademarks in a national database. It provides a list of the names found to be similar.
Legal Processes
Registration
- Sole Proprietorship/Partnership – Master Business Licence and business name
- Corporation – federal or provincial registration and a NUANS search
Certifications
- Licencing
- Permits
- Professional memberships
Operations
- Municipal regulations regarding: registrations, bylaws, insurance coverage, permits
Trademark
- Unique combination of words or designs
- Protects a service or product name (prevents others from profiting from your business’ reputation)
- Separate fees for filing, registration, and renewal
Harmonized Sales Tax (HST)
- Register when revenue exceeds $30K in a 12-month period
- File annually or quarterly using the ‘standard’ or ‘quick’ method
- Different criteria depending on the territory/province
Protecting Business Interests
It is important for you to review and understand your legal liabilities and responsibilities.
As a sole proprietor/partner:
- Protect yourself
- Research and obtain the appropriate liability insurance
As an incorporated business:
- Protect yourself
- Protect the corporation
- Record internal policies, procedures, processes, and decision
- Understand compliance requirements
- Avoid personal guarantees or collateral for loans
Corporate Roles
An incorporated business does not have unlimited liability.
As an entrepreneur, you may have liabilities depending on your role within the organization. Generally, there are three corporate roles entrepreneurs will take on. When you perform multiple roles, there is potential for conflict.
Shareholder
- Ownership, appointment of directors, share in proceeds of a sale of corporation
Director
- Strategic development, critical decision making
Officer
- Day-to-day operations
Hiring
People are an important part of your organization’s core strength. Requiring staff can happen quickly. For example, you may need a full- time receptionist, or someone to help you temporarily to handle workload during a busy season.
Should you hire contractors or employees? There are benefits and drawbacks to both and financial consequences of getting it wrong.
Contractors vs. employees
There will be a difference in cost and flexibility depending on whether you hire a contractor or an employee.
Protecting yourself
Here are some steps you can take to ensure you do not mis-classify a worker:
- Review and comply with the CRA criteria for classifying worker
- Consult with WSIB and CRA to get a determination before hiring
- Consult with a lawyer before hiring
- Ensure working relationship reflects the written agreement
