Hundreds are still without power in Dufferin, Peel and Wellington after high winds hit last night.
The wind also caused damage around the G-T-A.
According to the Hydro One website, a large swath of the region has power out.
Orangeville to past Grand Valley, south to Cheltenham and northeast to Mono are affected.
A small area just outside of Shelburne and to the north in Horning's Mills, and just south of New Tecumseth are also affected.
No official restoration time has been given, but Hydro One says crews are working on assessing the damage.
