De Icing in Markham, ON.
Markham sits in the GTA snow-belt fringe — 15-20 cm storms that drop nothing in Toronto are routine here, just 25 km north. Winters here deliver sustained snowfall through December, January, and February, and storm clusters can stack faster than ploughs can clear — and cul-de-sacs and curvilinear streets shape every routing decision. The local economy leans on IBM Canada, AMD, Markham Stouffville Hospital, and Aviva, which means our routes pre-treat IBM Canada's sites before residential bookings whenever a storm is forecast inside their shift change.
What a real Markham season demands
- Annual snowfall: 130 cm typical (standard-prairie band)
- De-icer cutoff: rock salt above −12 °C, calcium chloride below
- Response SLA: ≤ 3 hours from trigger
- Plowing trigger: 3 cm accumulation
- Winter temperature: -4 °C average (cool baseline)
- Inland factor: deep-cold reserve unit hot at the Cornell depot, winterised diesel blend below −20 °C
