If you plan on fishing tell someone where you’re going and when you’ll be back. The MNR warns that ice can be unpredictable this time of year.
The MNR mentions some things to look out for:
-If you’re travelling on the ice with a snowmobile there has to be at least 8 inches of clear blue ice
-Heavy snow on a frozen lake could insulate it and slow the freezing process, meanwhile, clear blue ice is the strongest
-Ice over flowing water like rivers and streams can be weaker than surrounding ice
