Commercial Disinfectant Fogging Services in Ontario

A fogging disinfection service disperses a hospital-grade disinfectant as a fine mist (fog) that fills a space and settles on every surface — including undersides, verticals, and gaps that manual wiping misses. CMG Clean uses ULV cold fogging and electrostatic spraying with Health Canada DIN-listed disinfectants, delivering complete 360° pathogen coverage for offices, clinics, gyms, schools, and warehouses across Ontario with fast, safe re-entry.

Commercial fogging in Ontario is typically priced at roughly $0.08–$0.20 per square foot, with a minimum call-out charge. A 2,000–5,000 sq ft office generally starts from $200–$500. Final pricing depends on facility type, disinfectant required, frequency, and whether it's an emergency outbreak response. Call 647-948-9415 for a free, no-obligation quote.

ULV (ultra-low volume) cold fogging disperses a disinfectant mist in the 5–50 micron droplet range, filling a room and settling across all surfaces and the air for whole-space coverage. Electrostatic spraying gives the droplets a positive electrical charge so they are actively attracted to and wrap around surfaces — ideal for high-touch, complex, or vertical surfaces. CMG Clean uses both and selects the right method for each facility.

Yes, when the right product and method are used. We apply Health Canada DIN-listed disinfectants selected for the environment — food-safe, non-corrosive formulations for kitchens and food-contact areas, and low-residue solutions safe around electronics and upholstery. Sensitive open electronics and exposed food are covered or removed before fogging as a precaution. Fabrics and soft furnishings are compatible with our fine-mist application.

After the disinfectant's label-specified dwell (contact) time — usually 10–15 minutes — the space needs ventilation before re-occupancy. Most Ontario facilities are safe to re-enter within 30–60 minutes of treatment. The disinfectants break down into harmless compounds after dwell, leaving no harmful residue.

Our Health Canada DIN-listed, hospital-grade disinfectants are proven effective against human coronaviruses (including SARS-CoV-2), influenza, norovirus, RSV, and a broad range of bacteria and fungi, achieving up to 99.9% pathogen reduction when applied at the correct concentration and dwell time.

Manual wiping only disinfects surfaces a cloth can reach; fogging and electrostatic spraying reach undersides, verticals, air spaces, and equipment gaps for complete 360° coverage in a fraction of the time. Frequency depends on your risk profile — outbreak response is on-demand, while medical clinics, gyms, and daycares often schedule monthly preventive fogging, stepping up during flu season or high-traffic periods.
