Of those, 169 cases have been marked resolved.

Over the weekend, public health reported its largest single-day jump with 75 cases in one day.

Officials said in an email on Saturday that the recent jump in cases was due to expanded testing in priority groups, especially people in long-term care and retirement homes.
