Requirements Overview

The most critical requirement for operating a supermarket in London, Ontario is Food Handler Certification (Restaurant Staff). This certification is legally required for anyone who handles, prepares, or serves food, and you cannot legally run a grocery operation without it. In addition, the Ontario Food Handler Certification is also mandatory across the province. These two CRITICAL certifications are non-negotiable and must be in place before you open your doors.

Beyond the critical certifications, you’ll need to meet health, safety, and regulatory standards. This includes Occupational Health and Safety Act Compliance to protect workers, Product Safety Compliance for retail products, and Retail Sales Standards and Consumer Protection to ensure fair dealing and accurate labeling. You’ll also need to plan for accessibility (AODA) compliance so customers with disabilities can shop with ease, and WSIB registration and coverage to support any workplace injuries. Finally, securing Commercial General Liability Insurance helps protect the business, staff, and customers from common risks.

On the business side, you must handle registrations and tax numbers. This includes registering for a Business Number (BN), obtaining a Business Licence, and registering your Ontario Business Name (ServiceOntario) if you’re trading under a name different from your legal entity. You’ll also need to set up GST/HST registration and payroll deductions registration. These steps establish your legal presence, enable proper tax handling, and ensure you’re compliant with provincial and federal rules.

Ready to move forward? Start by tackling the two CRITICAL certifications as a priority, then map out a quick compliance checklist for OHSA, product safety, and consumer protection. Next, set up your business registrations and tax accounts, and reach out to insurers and WSIB early. If you’d like, I can tailor a step-by-step 90-day plan with checklists and timelines.
