Parts of southern Alberta were treated to a light show on Saturday night and early Sunday morning as thunderstorms tracked through the region.
The unsettled weather was caused by the remnants of a low pressure system that tracked through Washington, Idaho and British Columbia.
Many took to social media to share their photographs and videos of the thunderstorms, which can be seen below.
