"The Delta variant is more transmissible and may be more risky", the modelling documents say.
Second doses of the COVID-19 vaccine will help control surges of the Delta variant in high-risk areas and minimize spillover to other areas.
Latest data also show Ontario has now surpassed both the U.S. and U.K.in relative terms when it comes to the percentage of the population who have received one dose of a COVID vaccine.
If Ontario continues to control COVID-19, the modelling suggests intensive care admissions will drop to below 200 bymid-July and normal hospital operations can resume.
"This is not a doomsday scenario ..."
But Brown said that he believes that it can be controlled by accelerating second doses in hot spot communities that are experiencing a rapid rise in Delta cases. "To be clear, we're not out of the woods just yet". "We have a really good chance of a good summer".
The province of Ontario is expanding eligibility for second doses of vaccines in regions where the Delta variant is prevalent.
Individuals in hot spots within Halton, Peel, Porcupine, Toronto, Waterloo, Wellington-Dufferin-Guelph and York public health units will be eligible to book their second Pfizer or Moderna doses through the provincial booking system as of 8 a.m. on June 14.
Finally, in the worst case scenario, the new more infectious variant would lead to a fourth wave of the pandemic in which daily case counts would rise exponentially and reach 2,500 by mid-August.
"Increasing vaccination from about 140,000 vaccines a day to about 180,000 vaccines a day does lower any curve that we look at", Dr.
While Ontario's COVID-19 situation has seen improvements, the more transmissible Delta variant remains a concern, with Dr. To date, 1,399,776 people have received two shots and are considered fully vaccinated.
As of today, the province's public health units, mass vaccination clinics, hospital sites, pharmacies, and physicians are reporting more than 10.6 million doses of COVID-19 vaccines administered.
