A tornado developed about 10 kilometres southeast of Gatineau Airport, Quebec early Sunday evening.

The tornado moved east along the Ottawa River before coming ashore on the Ontario side.

In the suburban Ottawa neighbourhood of Orléans, strong winds brought down trees and removed shingles on many homes with one person reportedly injured.

A thunderstorm also produced 2 centimetre hail in the area.

New Brunswick is not the only province experiencing severe flooding this spring – so are Ontario and Quebec.

The City of Ottawa declared a state of emergency this week as water levels rose along the Ottawa River.

The military was called in to help with flood mitigation efforts including sandbagging along with thousands of community volunteers.

In the western Laurentian mountains, the Rouge River is threatening to spill over the Bell Falls Dam and at least 60 homes have been evacuated downstream.

Due to the threat of flooding in several areas of the city, Montreal has also declared a state of emergency.

Environment Canada has confirmed two powerful tornadoes ripped through west end Ottawa before touching down again in Gatineau across the Ottawa River.

Officials say dozens were hurt and at least two residents are in hospital with critical injuries.

Tens of thousands were left without power after at least 80 utility poles either snapped or were damaged.

Meteorologists say severe thunderstorms spawned one twister classified as an EF-3 with winds up to 265 km/h while another tornado was an EF-2 with winds up to 220 km/h.

Tornadoes are not uncommon in Southern Ontario but storms of this strength are rare.
