Requirements Overview
The most critical requirement for operating a business in London, Ontario is Occupational Health and Safety Act Compliance. This is a legal requirement that shows you are protecting your staff and managing workplace risks. You cannot legally run your executive offices without putting proper safety practices in place, training your team, and following reporting rules under the Act. This requirement is non-negotiable and must be in place before you start formal operations.
In terms of day-to-day operations, you’ll need to address essential safety and permit-related items. This includes ensuring WSIB Registration and Coverage so employees are protected if injured at work, and obtaining a City business licence to legally operate from your location. If you plan to use a name other than your legal company name, you’ll also need Ontario Business Name Registration through ServiceOntario. In addition, you’ll want to respect employment standards for any staff (pay, hours, leaves) and privacy requirements for handling employee and customer data.

Registering for GST/HST is required or optional based on your sales thresholds, and Payroll Deductions Registration is needed to handle CPP/EI and other withholdings. If you’re conducting business under a name other than your corporate name, BN linked registrations, and the Ontario name registration will keep you compliant from day one.
