Taxation and Finance Ontario 4 Minutes Read · published May 26, 2026 Flag of Ontario

Retailers operating in St. Catharines, Ontario must follow federal and provincial sales tax rules while also maintaining compliance with municipal business licensing and by-law requirements. The City enforces local business licence rules and may require proof of tax registration or records; for federal and provincial GST/HST obligations retailers must register, collect and remit to the Canada Revenue Agency (CRA) according to federal rules. For city-specific licensing obligations see the City of St. Catharines business licences page Business Licences[1].

Keep separate records for sales tax amounts collected to simplify remittance and audits.

Penalties & Enforcement

Enforcement of sales tax remittance in St. Catharines involves two layers: federal enforcement by the CRA for GST/HST obligations, and municipal enforcement for business licence and by-law compliance. The CRA administers penalties and interest for late or missing GST/HST remittances and can assess administrative penalties; see the CRA guidance for specifics on obligations and consequences GST/HST for businesses[2]. The City of St. Catharines enforces its business licence and by-law requirements through By-law Enforcement and Licensing staff; penalties specific to municipal licence breaches are set out in municipal by-laws or licensing fee schedules and may be published on the City site.
