Vaughan hospital opens its doors to COVID-19 patients
A new hospital in Vaughan, Ont., began accepting COVID-19 patients on Sunday to help relieve pressure on other facilities in the Greater Toronto Area.
The Cortellucci Vaughan Hospital was originally scheduled to open in early February as the first brand new hospital — not a replacement of an older facility or a merger with an existing facility — in the province in almost three decades.
Cortellucci Vaughan won't immediately open for full service, according to operator Mackenzie Health.
Instead, the new facility will focus on its 35 ICU beds and 150 general internal medicine beds, which are currently earmarked for COVID-19 patients.
Mackenzie Health says that while the new hospital focuses on expanding intensive care capacity, its emergency department remains closed until the province's health-care system stabilizes.
The $1.7 billion hospital start with space for 35 intensive care patients and 150 acute care beds and aims to have 342 beds, Mackenzie Health said in a news release on Sunday.
The news comes as Toronto recorded another 517 new COVID-19 cases and 121 in York region on Sunday.
"Mackenzie Health is proud to provide a unique system solution in our collective fight against COVID-19," said Mackenzie Health President and CEO Altaf Stationwala.
"With the opening of Cortellucci Vaughan Hospital, our exclusive focus at this time is on creating additional space to care for critical and acute care patients, and to provide relief to our overstretched health care system. The province needed us to open Cortellucci Vaughan Hospital in this way, and we've answered that call."
Emergency child care expands to more frontline workers
The province announced on Sunday it would expand emergency child care to more front-line workers the government prepares to unveil plans for gradually reopening Ontario's economy.
The free child-care now available to health-care, education and postal workers will be extended to some construction workers and transit workers in Toronto, York Region and Peel beginning this Tuesday.
"Beginning this Tuesday, emergency child care will be extended to additional frontline workers in Toronto, York Region and Peel," Minister of Education Stephen Lecce said in a news release on Sunday.
Lecce said with the expansion, the Ford government aims to provide more support for key workers with children in Toronto, York Region and Peel in the week before they return to classes on Feb. 16.
"During this period of remote learning, our government is supporting these key workers by ensuring their children are well cared for."
"This will include construction workers working on essential projects that have been permitted to continue during the provincial shutdown, and transit workers who are unable to work remotely," Lecce said.
