Intense storm activity capsized as many as seven catamarans on Lake Ontario, forcing local police and fire departments to come to the rescue.
Halton Police say powerful winds overturned the boats Sunday and tossed at least four people into the water.
Police dispatched its marine unit, which was assisted by rescue boats from Hamilton and Peel police forces.
A Coast Guard auxiliary unit and the Burlington Fire Department were also involved in the rescue.
Everyone who ended up in the water had a life jacket and was picked up safely.
Hamilton police say it was a busy weekend for marine police and rescue agencies across the Golden Horseshoe.
Officers were called to deal with everything from flipped Seadoos to vessel collisions, capsized sailboats and people in the water.
No one was seriously hurt.
Police say these incidents underscore the importance of safe boating practices and proper safety equipment.
The Hamilton Police Marine Unit is reminding all boaters:
-Be sure to have a properly fitted lifejacket or personal flotation device (PFD) for each person on board
-Wearing your PFD is strongly encouraged. Like the seatbelt in your car, your PFD won’t work if you don’t wear it!
-Ensure you have all required safety equipment on board your vessel and that everything is in good working order.
-Always check the marine weather forecast before heading out, and return to port when signs of thunderstorms or other dangerous weather appear. You can check the marine forecast at: www.weather.gc.ca and monitor conditions on VHF Continuous Marine Broadcast channel 83B.
-Stay well clear of large commercial vessels
-Dress for the water temperature, not the air temperature. And be aware of the effects of cold water immersion. Hypothermia is a factor in Lake Ontario all year, even in the summer.
-Always maintain a good lookout and be aware of your surroundings.
-Never boat under the influence of alcohol or drugs!
For emergency assistance on the water, contact the Canadian Coast Guard on VHF radio channel 16 OR dial *16 on your mobile phone.
