Halloween Safety Tips for Trick-or-Treaters

Boo! But stay safe while you scare! With temperatures hovering near freezing and possible flurries, parents and kids need to prepare for a cold evening on the candy trail.

Dress Warm Under Costumes: Layer thermals under costumes to keep kids toasty without hiding their spooky style.
Reflective Tape is Your Friend: Visibility will be low under cloudy skies, so make sure kids have flashlights or glow sticks—and add reflective strips to costumes.
Waterproof Footwear is Essential: With possible wet snow or rain, dry feet will mean happier little ghouls.
Plan Your Route and Check the Weather: Stick to well-lit areas, and consider cutting the night short if the weather turns icy.
Watch for Icy Sidewalks and Steps: It’s the season of slips and spills—walk carefully!

A Friendly Reminder – No Booze Behind the Wheel

Halloween might be a time for treats, but drinking and driving is always a deadly trick. If you’re attending an adult gathering, plan a designated driver, call a cab or rideshare, or stay the night.

Northwestern Ontario roads can be slick this time of year, especially at night when temperatures dip and black ice forms. Let’s keep the roads safe for little goblins and grown-up monsters alike.

Weather Wardrobe Recommendations

This weekend calls for insulated jackets, hats, gloves, and waterproof boots. Costumes may need to be worn over coats or creatively adapted to keep kids warm without sacrificing their spooky look. Scarves and thermal socks are highly recommended—especially for longer trick-or-treat routes.
