TRENDING NOW: Severe thunderstorm captured on camera at Canada’s Wonderland

A severe thunderstorm was captured on camera this long weekend at Canada's Wonderland as customers hurried for shelter.

A major clean-up effort is underway following Saturday's fierce storm that left at least seven dead and hundreds of thousands without power after it swept across southern Ontario and Quebec.

Police say six deaths in Ontario were caused by falling trees as strong winds created widespread damage, while a woman in Quebec died when a boat she was in capsized in the Ottawa River near Masson-Angers.
