Requirements Overview
The most critical requirement for operating a media buying agency in Ottawa is Occupational Health and Safety Act Compliance. This is a legal must in Ontario, and you cannot legally run your business without putting safety and proper workplace practices in place. It’s non-negotiable and forms the foundation of how you hire, train, and manage staff, and how you run client projects responsibly.
Beyond safety, there are essential operational duties you’ll need to handle before you start taking on clients. These include meeting local zoning rules and obtaining the City of Ottawa business license, so your office and activities are allowed where you operate. If you have employees, you’ll also need WSIB coverage to protect your team, and you should have professional liability (errors and omissions) insurance to cover potential client-facing risks. You’ll want to follow privacy and communications rules as well, meaning PIPEDA compliance for handling personal data and CASL compliance for marketing messages. It’s also wise to align with Employment Standards Compliance to respect workers’ rights and ensure fair pay and scheduling.
For the business registration and tax side, you’ll need to set up and maintain your official identifiers. This includes registering your Business Number (BN) for tax and government dealings, completing Ontario Business Name Registration (ServiceOntario) if you’re operating under a specific name, and handling GST/HST registration as applicable. If you hire staff, you’ll also set up Payroll Deductions Registration. These steps ensure you can legally bill clients, remit taxes, and meet reporting requirements as you grow.
If you’d like, I can lay out a simple 90-day action plan to tackle these steps in order, including direct links to the right government pages and a practical checklist you can reuse as you scale. You’ve got this—with clear steps, you’ll be compliant and ready to win clients.
