Fiona's "shocking" destruction leaves 470,000 people without electricity in Canada.

After former hurricane Fiona struck Canada's Atlantic provinces, hundreds of thousands of people were left without electricity on Saturday. Officials described the damage as startling and devastating.

Authorities reported that after Fiona made landfall in eastern Nova Scotia at around 3 a.m., trees were downed, electricity poles were snapped in two, roofs were ripped off houses, and residences were washed away.

Fiona had hurricane-force winds of 90 mph as it made landfall close to Whitehead, according to officials.

Tim Houston, the premier of Nova Scotia, said on Saturday that the devastation was "shocking."

Prince Edward Island had a storm surge of almost 6 feet. 

 According to Premier Dennis King, the destruction is likely the greatest the province has ever experienced, and recovery will take weeks or longer.
