Ontario: New daily cases of COVID-19
Meanwhile, Dr. Peter Juni of Ontario's Science Table says health leaders are learning more about emerging COVID-19 variants. He says that overall, the rate at which new variants are emerging is on a downward trend.
This comes after the World Health Organization described the newest variant, mu, also known as B.1.621, as a "variant of interest."
While preliminary data has hinted that the variant could be less resistant to vaccine immunity, Juni said it's "not a headache."
In Ontario, mu makes up less than 1 per cent of all cases of the virus. Juni says mu is far less transmissible than the Delta variant, which continues make up the lion's share of Canada's COVID-19 cases.
"Delta is the one that is unfortunately, for all of us, dominating globally," Juni told CBC Radio's Metro Morning on Monday.
"What we don't want is new mutations of delta in the future."
