It’s all-hands-on-deck for Hydro One in the wake of a major ice storm that has left thousands without power.

Hydro One says it has deployed all available staff to work on getting power back on across Ontario.

And as almost 100,000 customers are still without power, the power utility has mobilized 1,400 crews and called back 300 workers from vacations.

Local utilities are also pitching in to help get customers back online.

Hydro One says it hopes to get most customers back online by tomorrow evening.
