Requirements Overview
The most critical requirement for operating a business in Mississauga is Occupational Health and Safety Act Compliance. This is a legal obligation for any business with employees in Ontario, and you cannot operate without putting in place safe work practices, training, hazard controls, and proper incident reporting. This requirement is non-negotiable and serves as the foundation for everything else you do.
Beyond safety, focus on mandatory operational controls. Make sure your workplace adheres to OHSA standards, and that you have WSIB coverage for work-related injuries. You’ll also need to follow Employment Standards for pay, hours, and leaves. For a computing infrastructure, data-handling and IT services, privacy and security are essential too: comply with PIPEDA Privacy Compliance, put in place Cybersecurity Standards and an Incident Response plan, and protect Data Privacy in all client work.
For business registration and taxes, you’ll need to get the right numbers and registrations in place. Register for a Business Number (BN) with the Canada Revenue Agency, set up GST/HST Registration, and arrange Payroll Deductions Registration if you have employees. You’ll also want Ontario Business Name Registration (ServiceOntario) and the appropriate Business Licence if your operations require one. Having these in order helps you bill clients correctly and stay on the right side of tax and corporate rules.
If you’re ready to move forward, take small, practical steps: create a simple compliance checklist, start with OHSA and WSIB, then tackle registrations in parallel. Consider consulting an accountant or business advisor to tailor these requirements to your specific services and team. With a clear plan and steady progress, you’ll be well on your way to a compliant, sustainable Mississauga operation.
