City of Ottawa and Hydro Ottawa officials are among those giving an update on cleanup and power restoration at 4 p.m. ET Tuesday, about 72 hours after a devastating, fatal storm plowed through the region.

More than 150,000 customers were still without power in the wider Ottawa-Gatineau region as of noon ET Tuesday.

Hydro Ottawa CEO Bryce Conrad said again Tuesday morning he hoped the vast majority of residents still without power would see it restored between Wednesday and Friday. Specific homes with major damage will take longer, he said.

Food kept in powered-down freezers has spoiled and there are challenges when it comes to getting fuel.
