De Icing in Chilliwack, BC.
Chilliwack sits at the eastern end of the Fraser Valley cold-outflow corridor — the city sees more freezing rain events per year than anywhere else in BC. 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 Canadian Forces Base Chilliwack, Sardis Schools, and Fraser Health, which means our routes pre-treat Canadian Forces Base Chilliwack's sites before residential bookings whenever a storm is forecast inside their shift change.
