Requirements Overview

The most critical requirement for operating a veterinary services business in Windsor is the College of Veterinarians of Ontario License. This license is required to legally practice veterinary medicine in Ontario, and you must hold it (and keep it in good standing) for anyone on staff who treats animals. Without this license, you cannot legally diagnose, prescribe, or perform procedures. It is non-negotiable and should be your first priority before opening your doors.

In addition to licensure, you must meet mandatory operational rules that impact day-to-day care. Ensure compliance with the Ontario Occupational Health and Safety Act to provide a safe workplace for staff and clients, and meet Veterinary Premises Standards for a properly equipped and maintained clinic. If your practice handles controlled drugs, you’ll need a Controlled Drugs and Substances License for veterinary use. Also implement privacy practices aligned with PIPEDA to protect client and patient information.

On the registration and tax side, you’ll need to obtain a municipal business licence from Windsor, and register your business name with ServiceOntario if you’re using a name other than your own. You’ll get a Business Number (BN) from the Canada Revenue Agency to handle taxes, payroll deductions, and other accounts; plan for GST/HST registration if you exceed the threshold; arrange WSIB coverage for staff; and secure professional liability insurance to cover potential errors or omissions.

Next steps: confirm your license with the College, contact Windsor’s licensing authority, and set up ServiceOntario and BN registrations. Draft simple safety, privacy, and client records policies, then align your accounting and human resources setup. With a clear checklist and realistic timelines, you’ll move from planning to a compliant, confidently run veterinary practice in Windsor.
