Power has been restored to all Hydro One customers who had been without it this morning.
Hydro One reports power went out for thousands of customers in Carlow-Mayo, Bangor, Brudenell, Lyndoch and Raglan, Hagarty, and Madawaska Valley at around 6:30am.
Power was fully restored for these customers just after 10:00am.
The outage was caused by a tree which had fallen on a main line.
