Requirements Overview
The most critical requirement for operating a paint and wallpaper retailer in Mississauga is Occupational Health and Safety Act Compliance. This is the baseline you must meet to protect your employees and customers, provide proper training, and maintain a safe store environment. It is a legal obligation and non-negotiable—without demonstrating OHS compliance you cannot legally run the business.
In practice, you’ll also need to cover mandatory operational requirements that relate to how you run the day-to-day business. Focus on health and safety in the workplace, plus the necessary permits and coverage. This includes ensuring WSIB registration and coverage if you have staff, and following Employment Standards Compliance for wages, hours, breaks, and other worker rights. You’ll also need to observe consumer protection rules for retail and product safety standards for any building materials you sell; if you plan to sell pesticides, you’d require the Pesticide Retail Sales License.
On the business and tax side, you must complete several registrations to operate smoothly. This includes obtaining a Business Number (BN) from the Canada Revenue Agency, securing a municipal Business Licence, and registering your Ontario Business Name (ServiceOntario) if you’re using a name other than your own. You’ll also need GST/HST Registration, Payroll Deductions Registration if you have employees, and ensure proper Retail Sales Tax collection and remittance as part of your tax obligations.
If you’re ready to get started, your next steps are practical and doable: contact ServiceOntario to register your business name (if applicable) and apply for a business licence; set up your BN and GST/HST account with the CRA; arrange WSIB coverage and payroll systems; and review Ontario consumer protection and product safety requirements for your product mix. You’ve got a solid path forward—take one step at a time and you’ll be on your way.
