He will be joined by Health Minister Tyler Shandro, Education Minister Adriana LaGrange, Justice Minister Kaycee Madu and Chief Medical Officer of Health Dr. Deena Hinshaw on Wednesday at 10 a.m.
"If exponential growth of COVID-19 in Alberta continues, it would begin to push the outer limits of even our surged and expanded hospital capacity within weeks", said Kenney in a televised address that was also livestreamed on the government's website and the premier's Facebook page Tuesday night.
The premier says the rules are necessary to arrest a surging wave of COVID-19 cases that will otherwise overwhelm the health system in the next few weeks.
She said while most kids don't experience serious illness from COVID-19, protecting them with a vaccine also helps protect their friends and family, who may be at higher risk of complications.
Barber shops, hairs salons, tattoo parlours and other personal wellness services must close Sunday.
Outdoor gatherings will be limited to five people with a strong recommendation they be restricted to no more than two family cohorts.
Customer capacity in retail stores, at 15 per cent of the fire code maximum, will be 10 per cent as of Wednesday. All workplaces with COVID-19 outbreaks will be ordered to close for 10 days, with the exception of critical workplaces, as of May 5th.
The province is also doubling the fine for Public Health Act violations to $2,000, and Kenney says there will be tougher enforcement for repeat offenders.
Alberta had 23,623 active COVID-19 infections Tuesday - the highest case rate of any jurisdiction in North America.
"The reason we are at this critical stage of the pandemic in Alberta, with record-high daily case counts and intensive-care numbers, is precisely because, for whatever reason, too many Albertans are ignoring the rules that we now have in place", he said.
In total, there are 226 Albertans in ICUs - more than the system had room for before the pandemic. "By opening bookings to everybody over 12 years of age, we are taking a huge step towards stopping the spike and hopefully putting this pandemic behind us for good", says Premier Jason Kenney.
There were 876 variants of concern identified and now account for 63% of all active cases.
At the height of Alberta's second wave in December, there were more than 900 in hospital, but never as many in intensive care.
Tuesday's new restrictions follow enhanced measures put in place for Alberta "hotspots" last Thursday, April 29, for regions in the province that are experiencing high case counts.
