Chief public health officer Dr. Michael Patterson says the person is isolating and doing well but did not say whether the person had travelled.
Patterson says contact tracing has started in the community of about 8,000 and his team is working to identify high-risk contacts.
As of 7 a.m. Thursday, all non-essential businesses, government offices and schools in Iqaluit must close and indoor gatherings are limited to a household plus five people.
Patterson says businesses and schools in all other communities in the Baffin Island region can stay open with strict social distancing.
The case in Iqaluit is the only active case of COVID-19 in the territory and over 3,400 Iqaluit residents have received one dose of the Moderna vaccine.
Iqaluit was the sole remaining capital city in Canada without a COVID-19 case until Wednesday’s announcement.
