At least two people have died and several have been injured after Hurricane Juan hit eastern Canada on Monday, causing blackouts and flooding.
The victims - one an ambulance driver - reportedly died after trees fell onto their vehicles.
A four storey apartment building collapsed in the port city of Halifax, trapping at least two people in the wreckage, officials said.
A state of emergency has been declared and several homes have been evacuated.
Plunged into darkness
The eye of the storm hit the south shore of Nova Scotia around midnight local time causing immediate flooding in the low lying areas along the coast and in Halifax.
The city was lashed by winds of up 140 km/h (87 mph), plunging homes into darkness as power blackouts spread across the region.
Television stations reporting on the hurricane abruptly lost their satellite links.
As the seriousness of the storm became more apparent, many homes were evacuated by local authorities.
There are reports that many trees have come down or have simply been uprooted.
Bridges are closed, the airport shut down and Halifax remains in a state of emergency.
The hurricane swept across Prince Edward Island, knocking out power in some places, although voting in a provincial election there went ahead.
"I have never seen something of this magnitude in my life," said Clifford Lee, a mayor on the island.
The hurricane was downgraded to a tropical storm early on Monday and forecasters have warned of up to three inches of rain.
