A lightning bolt struck as a storm chaser was filming an ominous-looking shelf cloud looming over Waterloo, Canada.

As the chaser pans across a field, a fork of lightning strikes followed by a loud clap of thunder.

The filmer told Newsflare: "The lightning strike was 100 metres away. The storm also merged with another storm producing an even longer line and with 70kmh+ winds. This uprooted trees in waterloo and caused power outages."

This footage was filmed on June 29.

Came off the great lakes in a line through Waterloo ON directly west and headed east through guelph.

Cape in excess of 3000 is rarely seen in waterloo guelph region. The storm continued to build through waterloo hence the lightning strike.

The lightning strike was 100 meters away. The storm also merged with another storm producing an even longer line and with 70kmh+ winds. This uprooted trees in waterloo. And caused power outages.
