Toronto, and York Region recorded their first deaths related to COVID-19 on Sunday, Public Health officials said.

The Toronto man and the woman from York Region were both in their 70s. They both died on Saturday.

The man had travelled to the United Kingdom. On his return, he was tested at a hospital in Toronto and immediately began self-isolation at home, according to a City of Toronto press release.

The man was reported to Toronto Public Health by the hospital and a case investigation was completed.

He later presented at the Trillium Health Partners, a Mississauga Hospital on March 14 and died on Saturday, March 21.

'Today is a very sad day,' Dr. Eileen de Villa says

"Today is a very sad day for us and especially the family and loved ones of the man who passed away," said Toronto's Medical Officer of Health, Dr. Eileen de Villa.

"We extend our sincere condolences to the family and friends of the individual who died this weekend. I'm asking everyone again to make every effort and take every opportunity to practice social distancing.

"Please stay home, stay safe and take care of each other," de Villa added.

'A tragic reminder that we are confronting a deadly virus,' mayor says

Meanwhile, Toronto Mayor John Tory says this first death of a Toronto resident related to COVID-19 is "a tragic reminder that we are confronting a deadly virus."

"I know the entire city will be saddened to learn this news and joins me in sending condolences to the loved ones of the Toronto man who has died," Tory said in a statement.

Tory has been in self-isolation since March 13, days after returning to Toronto from a trade mission in Britain.

He said the death of the Toronto resident is yet another reminder why it is so important that everyone continues to do everything they can to stop the spread of COVID-19.

"The advice from Toronto Public Health is simple: work from home where possible, stay home except to get essential supplies, and maintain social distance by keeping at least two metres (6 feet) from others," Tory said.

7 newly-confirmed cases in York Region

The death in York Region is that of a Markham resident who returned from international travel on Saturday, and died shortly thereafter.

"York Region extends deepest condolences to the family and loved ones of the individual," said Dr. Karim Kurji, Medical Officer of Health.

"This case speaks to the seriousness of the current situation and how as a community we need to continue working together to protect one another."

York Region also reported seven newly-confirmed cases of COVID-19 earlier Sunday, bringing the total number of confirmed cases in that region to 44.

Ontario gives hospitals new powers to redeploy staff

In other developments, the Ontario government is using its state of emergency declaration to give hospitals temporary new powers to respond to the pandemic.

These powers enable hospitals to redeploy staff between locations, to different areas within hospitals and to COVID-19 assessment centres without notice. Hospitals are now able to change work assignments and schedules, cancel vacations and let volunteers do "bargaining work."

Under what the government calls a "temporary order," hospitals would be able to override collective agreements when they redeploy staff and that power includes superseding provisions governing such things as layoffs, seniority and service and bumping.

"This temporary order would give hospitals the ability to cancel and postpone services to free-up space and valuable staff, identify staffing priorities, and develop, modify and implement redeployment plans," the government said.

The government said hospitals can do the following as they try to "prevent and alleviate" the spread of COVID-19:

Redeploying staff within different locations in (or between) facilities of the hospital.

Redeploying staff to work in COVID-19 assessment centres.

Changing the assignment of work, including assigning non-bargaining unit employees or contractors to perform bargaining unit work.

Changing the scheduling of work or shift assignments.

Deferring or cancelling vacations, absences or other leaves, regardless of whether such vacations, absences or leaves are established by statute, regulation, agreement or otherwise.

Employing extra part-time workers, or temporary staff, or contractors, including for the purpose of performing bargaining unit work.

Using volunteers to perform work, including to perform bargaining work.

Providing appropriate training or education as needed to staff and volunteers to achieve the purposes of a redeployment plan.

"When utilized by hospitals, these redeployment plans temporarily supersede the provisions of a collective agreement, including lay-off, seniority/service or bumping provisions," the government said in the statement.

"For example, currently a hospital would be required to post a lay-off notice and wait a period of time before being able to move a nurse or other unionized employee from an emergency department to a COVID-19 assessment centre," the government added.

"These measures would allow for the redeployment of staff to address the containment of COVID-19 without restriction or delay."

This time-limited order is valid for 14 days unless revoked or renewed in accordance with the Emergency Management and Civil Protection Act.

Ontario allows some child-care centres to reopen

As well, Ontario is allowing some child-care centres to reopen to help healthcare and frontline workers during the outbreak.

Doctors, nurses, paramedics, firefighters, police, and correctional officers are among those who can access the emergency child care, the government said in a statement on Sunday.

People who do work "essential to the delivery of core services in a municipality," will also be able to access child care, "as determined by the municipality."

The province ordered all licensed child-care centres to close as part of the state of emergency declared last week.

Ontario Education Minister Stephen Lecce said the province would keep a low number of children in each centre.

The centres will have to follow health and safety requirements and have a plan in place should any staff, children or parents be exposed to COVID-19, Lecce said.

People who are eligible are those who do "work of a critical nature in their service area or community," as determined by the education minister or his delegate in consultation with the relevant system manager or First Nation, he added.

Realtors urged to stop holding open houses

As officials continue to track the numbers of confirmed cases in the province, the outbreak is continuing to affect the economy.

On Saturday, the Ontario Real Estate Association called on all realtors to stop holding open houses during the province's battle with COVID-19.

The association is asking realtors to encourage their clients to organize virtual tours instead.

It says modern realtors have access to video teleconferencing and digital signings to go through the home-selling process, which could help curb the spread of the virus.

Employee at Petro-Canada/Tim Hortons tests positive

The province releases numbers twice daily about confirmed COVID-19 cases and Brampton Mayor Patrick Brown is doing his part to keep residents informed.

In a tweet early Sunday, Brown said an employee at a Petro Canada gas station and Tim Hortons outlet in Brampton, has tested positive for COVID-19.

The joint gas station and coffee outlet is located at 11980 Hurontario Street, near Mayfield Road.

Brown urges anyone who visited the location between March 9 and 20 to go into isolation.

"I would ask anyone who went here for gas, coffee or supplies to self isolate for 14 days," Brown said.

Petro-Canada has also tweeted about the confirmed case and said it has temporarily closed the location for cleaning. It has also asked store staff to go into isolation for 14 days.

"The health and safety of our partners, customers, employees and the communities we serve is the top priority for Petro-Canada," it said.
