Dode door bliksem in Ontario, Canada

One man was killed and a firefighter injured in separate lightning strikes caused by a series of severe storms that rolled through southern Ontario over the weekend.

A 25-year-old Brantford man was electrocuted on Saturday during a severe storm. He was riding an inner tube with two friends on Saturday afternoon on the Grand River, when lightning struck the water. All three were injured and taken to hospital, but the 25-year-old was later pronounced dead, Brantford police said. His name wasn't released.

Meanwhile, a firefighter was hurt while trying to put out a fire caused by lightning at a home in Markham, Ont., Sunday night. The roof of the home near 16th Avenue and Main Street was set alight at around midnight. Fire crews responded, and the firefighter fell off a ladder, police said. His injuries are not considered serious.

The lightning strike was delivered by the same weather system that prompted several thunderstorm warnings Sunday night for southern Ontario. It covered most of cottage country, through Oshawa, Pickering and west to Brantford, Simcoe and Norfolk areas. Environment Canada warned of winds higher than 120 km/h, hail and torrential rainfall in some areas.

The severe weather system has now moved northeast out of southern Ontario.
