Requirements Overview
The most critical requirement for operating a national security business in Mississauga is Occupational Health and Safety Act Compliance. This is a legal baseline you must meet to protect workers and the public, and you cannot operate without it. It is non-negotiable: you’ll need a solid safety program, proper training, incident reporting, and ongoing compliance with workplace rules before you start taking on work.
Beyond safety basics, there are mandatory operational requirements to keep things running smoothly. Prioritize health and safety, then align on the day-to-day setup that government and clients expect: ensure WSIB Registration and Coverage, and comply with Employment Standards (wages, hours, leaves, and other worker rights). If your activities require it, obtain the appropriate Business Licence and be prepared for Security Clearance and Screening as part of certain national security or government work, along with adherence to Government Program Administration Standards.
For business setup and taxation, you’ll handle registrations and numbers rather than contracts. You’ll need a Business Number (BN) from the Canada Revenue Agency to manage tax accounts and programs. If you operate under a name different from your legal entity, you must complete Ontario Business Name Registration (ServiceOntario). If you’re selling goods or services in Canada, you’ll register for GST/HST. And if you hire employees, set up Payroll Deductions Registration with the CRA to handle withholdings.
Next steps: map out a simple, practical compliance plan and start the registration process (BN with CRA, Ontario Business Name Registration if needed, and any licences). Check Mississauga’s licensing requirements, and, if government work is a target, confirm security clearance needs for staff. With a clear checklist and focused actions, you’ll be ready to operate confidently and pursue opportunities in the national security space.
