This is definitely a cause for celebration.

On Wednesday, the University Health Network posted a video on Twitter of the staff at Toronto General Hospital's Medical-Surgical Intensive Care Unit (MSICU) celebrating their first day without a single COVID-19 patient in almost 15 months.

"Thank you for your hard work, I feel like I'm going to cry now, our first COVID case was March 26, 2020, and today we are COVID free," said the unit's nurse manager, Denise Morris, in the video to thunderous applause.

Dr. Abdu Sharkawy, an infectious disease expert based at Toronto Western Hospital, announced on Twitter on Monday that his hospital's COVID-19 unit is shutting down, which he called "a testament to the benefit of following [public health] advice & the incredible impact of vaccines."

There's been more positive news on the COVID-19 front in Toronto lately. The city recorded its lowest single-day total of COVID-19 cases since September this week, and 20% of residents are now fully vaccinated.
