Which Businesses Need to Register?

How to Register a Business With WSIB

Information Required During Registration
Businesses preparing a WSIB application should gather their records in advance. Information may include the legal and trade names, CRA business number, contact details, business activities, owner or director information, date the first employee was hired, number of employees, and estimated payroll.

How Much Does Registration Cost?
There is no fee to complete WSIB registration directly with WSIB. However, businesses that require coverage must generally pay ongoing insurance premiums based on factors such as their business activity, classification, applicable premium rate, and total insurable earnings.
These premiums help fund Ontario’s workplace injury insurance system and support benefits and services for eligible workers who experience work-related injuries or illnesses.

Construction Businesses and Mandatory Coverage
Construction has additional rules under workers’ compensation Ontario requirements. Some people who own or operate construction businesses may need coverage even without employees.

Reporting Payroll and Paying Premiums
After completing WSIB registration Ontario, businesses must continue meeting reporting requirements. Employers report insurable earnings and pay premiums monthly, quarterly, or annually depending on their assigned frequency.
