Ontario has a thriving economy that focuses on technology and manufacturing, making it an attractive province for entrepreneurs.

Whether you want to start a cleaning service business in Toronto or a cab service business in Ottawa, you need to understand the legal requirements for incorporating a company in Ontario and the reporting requirements after its formation. This guide will highlight how to registering a company in Ontario, from the documents needed to the legal frameworks.

Why should I register a company in Ontario?

Legal protection for business owners: Registering a business offers limited liability to business owners. The company can own and purchase assets, properties, and equipment as a separate identity. It can also enter into contracts with its name and borrow and repay loans. In case of legal consequences or loan default, business owners’ assets are protected from creditors.

Name protection and recognition: In Ontario, the name of a registered company is protected. When starting a business in Ontario, a business owner must obtain a NUANS report, making registering a unique and distinct name for your company easier. Once registered, your company name cannot be used by other businesses. Registration makes it easier to prevent the misuse of your business name and create a well-recognized brand.

Access to funding and investment opportunities: Banks and investors find it easier to fund and invest in registered businesses. A registered company provides a formal structure, making it easier to access business loans. Investors also find it easier to invest in registered companies either during the startup stage or when the business has developed. The government also offers incentives and grants to registered companies. Companies can also raise funds by selling shares to new investors in exchange for equity.

Credibility and professional image: Many people work or purchase from registered businesses because they comply with government regulations. Registration enhances a business’s credibility with customers, partners, and investors and shows its commitment.

Tax advantages: The government offers tax incentives or deductions to registered businesses, which benefit them more than sole proprietors who pay taxes through personal income taxes. Companies can also charge and collect tax, including HST (Harmonised Sales Tax). This improves a company’s financial status, leading to profits.

What are the cons of registering a company in Ontario?

What factors should you consider

Compliance costs: Incorporating a company in Ontario can be costly in maintaining compliance. Your company must be compliant with various corporate regulations, including tax returns and other paperwork, which add up to costs, especially for small businesses.

Higher minimum wage and employment standards: Unlike other provinces, Ontario has relatively high minimum wage and employment standards, which increase labor costs and make it more challenging for small businesses or startups.

Regulatory burden: Ontario’s many regulatory obligations may burden you and increase administrative tasks. Also, depending on the type of business you are incorporating, the regulatory burden may increase if you have to obtain any licenses or permits.

Increased liability: Incorporating an LLC in Ontario offers limited liability; however, it makes it more challenging to control and manage the company’s finances.

High taxes: Paying federal and provincial taxes makes keeping finances and profits afloat challenging. This makes it hard for startups and small businesses to stay competitive in the market. You can incorporate federally or provincially to stabilize your finances and not pay taxes.

What types of business structures can you register in Ontario?

In Ontario, several business structures exist, including sole proprietorship, partnership (general and limited), corporation, and limited liability partnership (LLP).

Sole proprietorship: An individual in Ontario operates this business under a business number or unique business name. This is the most inexpensive business starting method since it has fewer registration requirements. However, it does offer the least amount of protection. The structure provides unlimited liability, and the business owner is responsible for paying the company taxes since the business’s profit is integrated into the owner’s income.

Partnership: You can form either a general or a limited partnership in Ontario. A general partnership is a business that starts to generate profit. Partners agree in either writing, orally, or “implied by action’. ‘Implied by action’ implies a mutual desire to engage in a business venture to generate profit. This retains personal liability for the partnership deal.

A limited partnership has the same objective as a general partnership but provides two types of partners: general and limited. General partners are responsible for the partnership’s day-to-day operations, while limited alliances are responsible for investing or contributing property.

A limited partnership is liable for the amount of capital invested in the partnership.

Corporation: A corporation structure offers limited liability, like limited liability companies (LLCs). It allows you to operate within the province and protects your name in Ontario. There are several types of corporations in Canada, including Canadian-controlled private corporations (CCPC), other private corporations, public corporations, and corporations controlled by a public corporation.

Limited liability partnership: A limited liability partnership is a business structure that operates like a limited partnership. However, LLP is permitted to persons who carry on a law-recognized profession. There are three conditions to be met to establish an LLP which are;

  • Permission to establish an LLP cannot be implied based on the Act’s silence.
  • The body that governs the professional order has to require the maintenance of liability insurance.
  • The name of an LLP is registered under the Business Names Act.

What is a provincial incorporation

Choose a business structure

We have listed various business structures that entrepreneurs can form in Ontario. Choose a business structure that aligns with your business needs and future goals.

Choose a name for your business

Choose a distinct business name for your business. You can select a numbered or word name for your corporation. A numbered name is a unique number assigned by Corporations Canada, serving as your corporate identity (for instance, 87654321 Inc.). In contrast, a word name may incorporate letters, symbols, and numbers. It is essential that your proposed name is distinctive and does not create confusion with existing names or trademarks. Additionally, the name must not include any prohibited terms.

A corporate word name comprises three essential components:

  1. Distinctive element: The name should be original, creative, and unique, differentiating it from other corporations.
  2. Descriptive element: This component reflects the nature of your business or industry.
  3. Legal element: This indicates the legal status of your company, typically represented by terms such as “Corp.,” “Inc.,” or “Ltd.”

When incorporating a business with a word name, obtaining and submitting a NUANS report to Corporations Canada is necessary. The NUANS (Newly Upgraded Automated Name Search) report conducts a name search against Canadian databases, registries, trademarks, and other existing corporate names. This process ensures that your selected name is distinct from any registered entities in Canada, including those incorporated at the provincial level.

Create your articles of incorporation

This document outlines the essential structure and regulations governing the company once it is established. Typically, it is submitted to either provincial or federal authorities in Canada.

The ability to customize the Articles of Incorporation allows you to address your business’s specific requirements. You may tailor the document to include:

  • The distinctive name and branding of your company
  • Information regarding share ownership and any transfer limitations
  • The number of directors responsible for managing the corporation
  • Any particular restrictions or guidelines pertinent to your business
  • Additional clauses that align with your company’s unique objectives and aspirations

By meticulously drafting your Articles of Incorporation, you can ensure that your new enterprise is strategically planned and complies with all requisite legal standards.

Establish a registered office address and appoint directors

All companies that incorporate in Canada must establish a registered office address in Canada. It is necessary to designate a primary registered office and appoint at least one director, although additional directors are required. The registered office is the official location for receiving all company documents. You are required to provide the names and addresses of the directors, along with their residency status in Canada. It is crucial to verify that all directors meet the required eligibility criteria. Furthermore, you must submit information concerning individuals who hold significant control over the corporation, which may encompass shareholders, directors, or officers.
