The Mattagami River is unpredictable this time of year when it comes to ice safety. Because of the moving current, the ice could be thick in one spot, and not in another. River ice is also weaker than lake ice for the same reason. Spokesperson for the Timmins Police, Kate Cantin, says to make sure you check the thickness before putting any weight on the ice. In general, transparent, blue, or clear ice is typically safe. If the ice is white and grey, stay off.

Cantin says to keep yourself safe when ice fishing or snowmobiling, tell someone where you’re going to be. Also check for cracks or flowing water on the ice before you go on to it, and make sure the colour of the ice is consistent.
