ANGUS, Ont. -- Provincial police say there are reports of some minor injuries after severe weather ripped through the central Ontario community of Angus.

OPP Sgt. Peter Leon says he hasn't heard that anyone suffered a life-threatening injury as a result of the storm that hit the town Tuesday evening.

Leon says at least 20 homes, possibly more, were significantly damaged, and photographs posted on social media sites such as Twitter and Facebook show damage to roofs and walls of houses.

Leon said officers were going door-to-door in the affected area to make sure no one was trapped or injured.

Environment Canada had issued tornado warnings for several communities in the area as a line of severe thunderstorms with embedded tornadoes moved into the Lake Simcoe region.

Locally, tornado warnings began at 3 p.m. in southern Bruce County, including Saugeen Shores and Kincardine.

As the storm system moved east, areas around Hanover and Dundalk were added to the warning just before 4 p.m., and extended northward to Owen Sound around 30 minutes later.

By 5:20 p.m., the warnings for southern Bruce County and Owen Sound were cancelled, but regions near Wingham, Listowel, Mount Forest and Arthur were added to the alert.

The warning was extended to Guelph before 6 p.m., cancelled everywhere except Guelph by 6:20 p.m., and ended entirely by 6:45 p.m.

A separate system prompted tornado warnings for Brant and Oxford counties, including Brantford and Woodstock, at 5:30 p.m, ending before 6 p.m.

Local damage reports were not immediately available.

Environment Canada says the storms were bringing wind gusts of over 100 kilometres per hour and large hail was likely.

Leon said OPP and Barrie police officers, as well as firefighters and paramedics were making sure residents were OK.

"The primary focus right now is addressing those homes where we have individuals that could be still in a residence -- we want to make sure that nobody's trapped."
