A line of thunderstorms is coming through southern Ontario.
There is a severe thunderstorm warning in place for northern York and Durham Regions, as well as areas outside of the GTA. Those areas include the Orillia and Peterborough areas.
The thunderstorms are rushing through in about 15 minutes, followed by an hour or more of heavy rain.
Environment Canada says there are reports of hydro pole and roof damage near Laurel, a few kilometres northwest of Orangeville.
Meteorologist Peter Kimbell says that it looks like this was from a down burst of wind, as opposed to a tornado. They are still working on confirming the extent of the damage and the cause.
There is a second system moving through southwestern Ontario, with warnings in place in the London and Woodstock areas.
