These are the first cases of the omicron variant confirmed in Canada, coming just days after the country implemented new travel restrictions.
Two persons who recently entered Canada from Nigeria have been detected to have omicron variant of the coronavirus in Ottawa.
The Ontario government announced this on Sunday.
"Today, the province of Ontario has confirmed two cases of the omicron variant of COVID-19 in Ottawa, both of which were reported in individuals with recent travel from Nigeria. Ottawa Public Health is conducting case and contact management and the patients are in isolation," the statement said.
These are the first cases of the omicron variant confirmed in Canada, coming just days after the country implemented new travel restrictions on foreign nationals who had visited several countries in southern Africa over the preceding two weeks.
Those travel restrictions went into effect on Friday. The omicron variant was first identified by South African researchers and has provoked global concern.
Little is known about the new variant, dubbed omicron by the World Health Organization and labelled as a variant of concern. It is being linked to a rapid rise of cases in a South African province.
It is not known at this time whether the variant is more transmissible, or more dangerous to the health of those who catch it, than other coronavirus variants.
"The best defence against the omicron variant is stopping it at our border. In addition to the measures recently announced, we continue to urge the federal government to take the necessary steps to mandate point-of-arrival testing for all travellers irrespective of where they're coming from to further protect against the spread of this new variant," said the statement from Ontario Health Minister Christine Elliott and Dr. Kieran Moore, the province's chief medical officer of health.
The provincial government urged residents to get vaccinated, including with booster doses, and to continue following public health guidance.
"Ontario is prepared and ready to respond to this new variant."
More confirmed cases likely: health minister
In a statement released Sunday, federal Health Minister Jean-Yves Duclos said the confirmation of two omicron cases is a signal that the country's monitoring system is working but to expect more cases of the variant.
"As the monitoring and testing continues with provinces and territories, it is expected that other cases of this variant will be found in Canada," Duclos said.
