Toronto Police and the Marine unit are warning people to stay off the ice, no matter how frozen you may think it is.
This, after a picture was sent in to NEWSTALK1010.com apparently showing a man skating on Lake Ontario in Toronto Harbour.
Police say it's becoming an increasing, and disturbing trend.
"Unless you have the expertise and the tools to confirm the ice thickness in various parts, you really don't know," says police constable Wendy Drummond.
Calling it, "a dangerous game," she tells NEWSTALK 1010 that the further out you go, ice conditions can change very quickly.
And if you fall into the Lake at this time of year, experts say you have mere minutes before you succumb to hypothermia
