Strong to locally severe thunderstorms associated with a cold front
raced across southern Ontario Wednesday. There were numerous reports
of wind damage, particularly near Lake Erie and in the Toronto area.
There was also a report of wind damage in the Algonquin area.

Near Lake Erie, significant damage was reported near the towns of
Jarvis and Waterford after 3 PM. Approximately 1 km to the west of
Jarvis, several trees were uprooted or sheared apart. Some of the
branches were embedded into the roof of a house. As well, the porch
of the house and a nearby barn were destroyed. Nickel to quarter
size hail was also reported.

Approximately 3 km to the south of Waterford, numerous trees were
uprooted or sheared off halfway up. As well, a car was crushed by
trees and shingle damage was reported.

The thunderstorms crossed the Toronto area shortly after 4 PM. Most
of the damage consisted of downed trees and power lines due to high
winds. Power outages were reported by more than 10 000 customers.

In the south end of Algonquin Provincial Park near Little Hay Lake,

Not much in the north-end of St. Catharines here... dark clouds, rain, gusty winds.

I was watching it approach on radar and it seemed to have a big line that split right as it came near.
