Cold-Weather Security Operations: A Playbook for -40 °C Sites

Vehicles, radios, PPE, and rotation schedules that actually survive Northern Canadian winter.

Every security company can hand you a glossy proposal in June. The test is January. When ambient temperatures pass -30 °C and windchill drives sensible exposure limits below three minutes, most of the equipment and doctrine imported from southern-Canadian operators simply fails.

This is the operational playbook Maple uses across NT, YT, and NU. It is not a marketing document — it is what our supervisors distribute at fall pre-season briefings.

Radios: handheld batteries drop capacity by roughly 40% at -30 °C. Officers carry spares in inside chest pockets, warmed by body heat. Vehicle-mounted repeaters are the backbone; handhelds are secondary.

Rotation: outside foot-post rotations run to a maximum of 20 minutes at -35 °C ambient. At -45 °C ambient, the post is closed and coverage shifts to vehicle-based patrol with pre-arranged safe interiors.
