Saugeen Shores police are reminding area residents that no ice is safe to be on.
The word of warning comes after a person fell through the ice and into the water near Chesley Street in Southampton on Boxing Day.
The person was able to get out safely and did not require medical attention, police said.
Police are now advising people to stay off of waterways, stating "no ice is safe."
The Canadian Red Cross has previously stated that people should only skate on ice that is 20-plus centimetres thick. One way to determine ice thickness is by its colour. Clear blue to black ice is the strongest, while white opaque or snow ice should be avoided. Grey ice indicates the presence of water.
The agency stated that ice thickness is never consistent with the weakest ice in the centre and along the edge of the water. People should avoid going out on streams and flowing water, even if it looks frozen. Ice that has recently frozen, thawed and then frozen again should also be avoided.
