Coast guard issues warning about aquatic event on St Clair River on Sunday
The Canadian Coast Guard and its American counterpart are issuing a joint warning for people not to take part in the annual Port Huron float down on the St Clair River between Ontario and Michigan.
The American event on Sunday involves people floating down the river on rafts.
But the Canadian and American coast guards issued a joint letter on Saturday warning of the risks to people who are taking part.
The letter cites factors including a fast moving current, a large number of participants, a lack of lifejackets, water temperature, and limited rescue resources.
It says those conditions can result in serious injuries or fatalities.
It points out that last year high winds and a heavy downpour led to some 1500 participants inadvertently landing on the Canadian side around Sarnia.
