A big, bright flashing ball of light was spotted in the sky by hundreds of people as many claimed it was a meteor .
Intriguing footage shows a huge light filling the sky and expanding from a ball into a luminous white semi circle in skies over Canada.
People took to social media to report the sighting, which was apparently followed by a 'loud boom' noise.
Some said they could even feel their houses shaking on Monday night, at about 10.15pm.
