Hydro One employees worked tirelessly to restore power to approximately 500,000 customers affected by the major storm system that began on April 14. The system moved across Ontario from Windsor to the Quebec border and brought rain, ice accumulation of up to 30 mm, snow and significant wind gusts as strong as 100 km/hr in some areas. The efforts of employees from across the company resulted in a new record for Hydro One, restoring power in four days. This surpassed the previous six day restoration effort from the last, large scale March 2016 ice storm that earned Hydro One recognition from the Edison Electric Institute (EEI).
