Environment Canada has ended a severe thunderstorm watch issued for Toronto and parts of the GTA on Saturday.
Peel, Halton, Durham, and York regoins are also in the clear.
Meteorologists say conditions were favourable for the development of dangerous storms with strong wind gusts, large hail and torrential rain.
A line of severe storms did just that around the GTA on Friday evening.
There were reports of heavy flooding in parts of Markham, and hail in the Newmarket area.
