Daily air quality, pollen & slush risk — and what each means for your facility's cleaning schedule.
Updated 11:14 AM · Via Environment Canada & Health Canada
Air quality, pollen, and precipitation conditions are all favourable across the GTA. Standard cleaning schedules are appropriate. No adjustments to entry mat rotation, HVAC filter inspection, or floor care frequency are needed today.
Higher AQHI means more outdoor particulates enter buildings through doors, HVAC systems, and clothing. At 4+, entry mat and filter attention increases.
Pollen and slush are the two most common sources of floor soiling beyond normal foot traffic.

The GTA Cleaning Conditions guide is published daily by Zusashi Maintenance, a commercial cleaning company serving the Greater Toronto Area since 2007. We built this tool for facility managers, property managers, and operations teams who want a single morning check-in to know whether today's conditions require any adjustment to their cleaning program.
Air quality data is sourced from Environment Canada's AQHI monitoring network. Pollen data from Health Canada and the Weather Network. Salt and slush risk is derived from Environment Canada weather forecasts and road condition reports. This page is updated manually each morning — automated data feeds are in development.
