The vast majority of Ottawa residents still without power after a powerful weekend storm are expected to get their hydro back today.

Hydro Ottawa says it's aiming to have the bulk of its system up and running by the end of the day, with smaller pockets to be recovered over the weekend.

It warns, however, that weather may affect restoration efforts if more severe wind, rain and thunderstorms occur.

Meanwhile, Hydro One has said customers in the Bancroft, Perth and Tweed regions are expected to be without power for several days.

At least 11 people died as a result of the storm that swept across Ontario on Saturday.

The latest death, reported Thursday, was that of a 58-year-old man who provincial police say was struck by a falling tree in a remote area of the Municipality of Marmora & Lake.
