Toronto, the largest city in Canada, is moving into lockdown -- its highest alert, what it calls grey status -- as it tries to mitigate an increasing coronavirus emergency.

The Peel Region, just west of Toronto and including Mississauga, will also be placed in the grey status.

As part of the designation, public or social indoor gatherings are not allowed. Weddings, funerals or religious services may have up to 10 people indoors. All outdoor gatherings cannot include more than 10 people.

Also, restaurants and bars may have no indoor or outdoor service though takeout is permitted. Essential retail, like pharmacies and grocery stores, can open, but at 50% capacity. All other retail is closed except for curbside pickup.

Casinos, movie theaters and museums will all be closed. Media production facilities, including Toronto's thriving film industry, can only operate with proper social distancing on set.

Cases in Toronto have gradually increased since maintaining a seven-day average of under 100 per day through most of August. The city reported a one-day high of 1,581 cases on Nov. 14 and the seven-day average reported Friday was 1,373 per day.

States reported more than 1,800 deaths for the third day in a row on Friday, according to The COVID Tracking Project.

There were 1,862 deaths reported.

Daily COVID-19 tests, cases and current hospitalizations broke new records on Friday, the tracker said, surpassing all-time highs reached Thursday.

States reported over 1.9 million daily tests and 192,805 new cases, and 82,178 people are currently hospitalized with COVID-19, according to the tracker. 

Three states are reporting over 500 hospitalizations per million people: North Dakota, South Dakota and Nebraska.

Donald Trump. Jr. is the latest person connected to the White House to test positive for the coronavirus, a spokesman confirmed to ABC News.

“Don tested positive at the start of the week and has been quarantining out at his cabin since the result. He’s been completely asymptomatic so far and is following all medically recommended COVID-19 guidelines,” the spokesman said in a statement.

The president's eldest son is the second of his children to test positive for the virus, following Barron Trump's diagnosis last month.

The U.S. Food and Drug Administration announced Thursday that its vaccine advisory committee will meet Dec. 10 to discuss the request for emergency use authorization of Pfizer's COVID-19 vaccine candidate.

The public meeting will be a chance for both FDA career scientists and members of the independent advisory board to ask Pfizer questions about its product. 

After that, the board will make a recommendation, which the FDA will take into account when it decides whether to authorize the vaccine.

Officials said they cannot predict how long the FDA's review will take, but that it will be "as expeditiously as possible, while still doing so in a thorough and science-based manner."

A COVID-19 patient in the intensive care unit at a Utah hospital brought staff to tears when he played his violin for them to show his appreciation and help lift their spirts.

Grover Wilhelmsen, a retired orchestra teacher, was intubated and unable to talk, but he used pen and paper to communicate with one of the nurses taking care of him at Intermountain Healthcare's McKay-Dee Hospital in Ogden, Utah.

"Toward the middle of my shift he wrote, 'You know, I really want to play here at the hospital. What do you think about my wife bringing in my violin and viola?'" Ciara Sase, a registered nurse at McKay-Dee Hospital, said in a press release from Intermountain Healthcare. "I said to him, 'We'd love to hear you play, it would bring so much brightness and positivity into our environment.'"

Sase and her coworkers talked through the details of Wilhelmsen's request and, after getting approval from doctors, the team agreed they could manage it as long as Sase stayed in the patient's room to monitor him while he played.

Wilhelmsen's wife of 47 years, Diana, brought his violin and viola into the hospital, along with some music books. Wilhelmsen then played church hymns and other songs including the Tennessee Waltz.

Because all ICU rooms have glass doors that are kept closed, Sase turned on her Vocera communication device so her colleagues on the other side could hear Wilhelmsen play.

"About a dozen caregivers gathered to watch and listen in the ICU," she said. "It brought tears to my eyes. For all the staff to see a patient doing this while intubated was unbelievable."

Matt Harper, another registered nurse at McKay-Dee Hospital, was one of the staff members who came to listen.

"It was honestly shocking to be there when he picked up the violin. It felt like I was in a dream," Harper said in the press release. "I’m used to patients being miserable or sedated while being intubated, but Grover made an unfortunate situation into something positive. This was by far one of my favorite memories in the ICU that I’ve had. It was a small light in the darkness of COVID."

Wilhelmsen played multiple times over the course of two days before he became too ill and required sedation. Sase said she would be in the room with him for about two hours each time he played.

"Afterward, I told him how thankful we were and how much it meant to us," she said. "Before he took a turn for the worse, he continued to write things to me such as, 'It’s the very least I could do,' and 'I do it for you guys because you all are sacrificing so much to take care of me.'"

After spending more than a month battling COVID-19 at McKay-Dee Hospital, Wilhelmsen was discharged from the ICU to a long-term acute care facility where he's expected to recover from the disease.

"He truly is special and made a mark on all of us," Sase said. "When I started to cry in the room after he was done playing, he wrote to me, 'Quit crying. Just smile,' and he smiled at me."
