Requirements Overview

The most critical requirement for operating a business in Mississauga is Occupational Health and Safety Act Compliance. This is a legal obligation you cannot operate without. The OHSA governs how you keep workers safe, requires safety training, hazard assessments, incident reporting, and clear safety policies. It applies even if you have volunteers. Non-negotiable: put a safety plan in place from day one, assign accountability, train staff and volunteers, and keep records up to date.

Mandatory operational requirements cover health, safety, and permits, and should be grouped together. Along with OHSA, you’ll typically need WSIB registration and coverage if you have staff or volunteers, and you should carry appropriate insurance—professional or general liability—so you’re protected in daily operations. You may also need a local Mississauga business licence and any sector-specific permits. If you operate as a charity, Registered Charity Status may apply, but the core safety and insurance requirements come first.

Business Registration & Tax: Set up your Business Number (BN) with the Canada Revenue Agency to handle taxes and payroll deductions, and register your Ontario business name with ServiceOntario. You’ll likely need GST/HST registration if you meet the threshold or expect to charge tax. If you have employees, you’ll manage payroll deductions and remittances through the BN. Also check whether a Mississauga licence is required based on your activities.

Next steps: start with the critical item, then tackle registrations in a practical order. Use CRA and ServiceOntario resources, and consider a quick chat with a local business adviser or Mississauga’s small-business support services. With a clear plan and checklist, you’ll be compliant and ready to launch with confidence.
