A warning to the public about the condition of the ice on Lake Simcoe. A man driving an ATV over the lake last night, broke through the surface and his machine sank in about 4 feet of water. The driver was near the shoreline in Gilford at the time. Police say the driver of the ATV was able to escape unharmed. His machine was later pulled from the lake. Police remind residents that ice conditions remain unsafe and unreliable and that safety should always be a priority.
