Clear ice should be a minimum of 10cm (4”) for walking and ice fishing, 12cm (5”) for one snowmobile or ATV, 20-30cm (8-12”) for a car or small pickup, 30-38cm (12-15”) for a medium truck (source: Lifesaving Society)
Fish with a buddy
Be prepared for an emergency – wear ice picks or a floater/survival suit, and have a whistle and cell phone on hand
Let someone know where you will be and when you plan to return. This should include where your vehicle will be parked, what route you plan to take and any stops you plan to make
Stay off rivers and away from locks, where ice is less stable. Ice conditions in areas of moving water or spring fed lakes can be unsafe at any time, ensure the ice is safe before venturing out.
