Mandatory coverage in construction

If you are an independent operator, sole proprietor, partner or executive officer, and you work or carry on a business in construction, you must have WSIB coverage (some exemptions apply). Learn about Mandatory coverage in the construction industry.

If you do not work in construction, you are not automatically eligible for WSIB coverage and you may apply for Optional Insurance. Contact us for more information at 416-344-1000 or 1-800-387-0750, Monday to Friday from 7:30 a.m. to 5:00 p.m.

If you are required by law to register, private coverage is not a substitute.

Benefits of registering

Registration provides workplace insurance coverage for all of your workers, gives you peace of mind, and lets you access experts in health and safety.

The benefits of registration are clear:

  • no-fault insurance
  • greater protection, since in most cases workers can't sue you following a work-related injury or illness
  • benefits for your workers - WSIB insurance replaces lost earnings and covers health care costs resulting from work-related injuries and illnesses
  • help in returning your workers to the job - and returning your business to full productivity
  • training and prevention programs

Note for sole proprietors, partners and executive officers

You are not automatically eligible for WSIB coverage. For more information, call us at 416-344-1000 or 1-800-387-0750.
