Salt Spreaders in Sarnia, ON.
Sarnia's Chemical Valley refineries require salt-free de-icing on plant roads — calcium acetate is standard within the security perimeter. Winters here mix freeze-thaw weeks with hard cold snaps, so ice and pack are bigger factors than raw snow volume — and cul-de-sacs and curvilinear streets shape every routing decision. The local economy leans on Chemical Valley refineries, Lambton College, and Bluewater Health, which means our routes pre-treat Chemical Valley refineries's sites before residential bookings whenever a storm is forecast inside their shift change.
