How to start a construction business in Ontario
Table of contents
The construction industry in Ontario is a dynamic, competitive sector that can offer both opportunities and challenges to entrepreneurs. From general contracting to highly specialized restoration, there are many different kinds of construction businesses. Before starting your business, think about the types of construction services your company will provide. Based on your services, there are several steps you will need to take in order to start your business.
When you start a business there are several things to consider before you can sell your product or service. Most businesses in Ontario need to complete a minimum of three basic steps:
- Find out what licences and regulations apply to your type of business
- Choose a business structure and register or incorporate your business
- Determine if you will need to collect and remit HST
Our business start-up guide will give you more information on these steps and other basic requirements for starting a business in Ontario.
Starting a Business
Your business may need licences and permits from the federal, provincial and municipal levels of government.
In addition to the information you will find in this guide, you can use the Canada Business Permits and Licenses Search, powered by BizPaL, to find licences and regulations that may affect your business. You can also contact us to speak to someone about starting your business.

Labour regulations and workplace safety
If you carry on a business in the construction industry as a contractor, sub-contractor, sole proprietor, partner in a partnership, or an executive officer in a corporation, you must register with Workplace Safety and Insurance Board (WSIB) for mandatory insurance coverage. There are some exceptions to the mandatory coverage.
WSIB - mandatory coverage in the construction industry
If you hire an independent contractor to work with your business, you must make sure that they have been issued a Clearance Certificate from the Workplace Safety and Insurance Board (WSIB). The certificate is issued free of charge and proves that the contractor is registered with the WSIB and has an account in good standing. The certificate also clears you of financial responsibility for WSIB payments.

If you sell goods and services in Ontario, you may need a business number to collect and remit the Harmonized Sales Tax (HST). Most businesses that make less than $30,000 in any 12-month period are not required to charge HST; however, you can register voluntarily and claim input tax credits. Speak with the Canada Revenue Agency (CRA) for more information.
