Coronavirus in Canada


As provincial and territorial governments scale back COVID-19 data collection and reporting, some experts are calling this the most uncertain wave of the pandemic to date.

  • Governments that reduced public reporting frequency from daily to weekly – including B.C., Alberta, Saskatchewan and Manitoba – attribute the shift to there now being more value in observing trends over time, rather than daily fluctuations.
  • But experts say Canada is now flying blind as the Omicron sub-variant BA.2 fuels a resurgence of cases. “The absolute worst time to change your data streams is on the rise of a new variant, and that’s exactly where we are,” said Sally Otto, a professor at the University of B.C. and a member of the independent B.C. COVID-19 Modelling Group.

Boosters: Many health experts say they are concerned by the slow uptake of first booster shots, warning that two doses of COVID-19 vaccines don’t offer sufficient protection against the Omicron variant. Only 57 per cent of those 18 and older have received a booster shot so far.


Coronavirus around the world

  • More than 100 quarantine facilities have been set up in China’s most populous city Shanghai for people who test positive but have few or no symptoms. In one of these facilities, located within a convention centre, the lights stay on all night and there are no hot showers.
  • India’s number of daily COVID-19 cases nearly doubled today from yesterday to more than 2,000 for the first time in a month, government data showed.
  • A federal judge in Florida ruled today that a U.S. mask mandate on public transportation is unlawful, overturning the Biden administration initiative. Last week, health officials extended by 15 days the mandate requiring travellers to wear masks on airplanes, trains, and in taxis, ride-share vehicles or transit hubs.

Coronavirus and business

China’s economy grew 4.8 per cent in the first quarter of this year – better than expected – but also showed signs of a slowdown brought on by the war in Ukraine and COVID-19 lockdowns in Shanghai and other cities.

  • While Shanghai’s port and some factories have continued operating, economists have warned the restrictions are already taking a toll on the wider economy, with logistics chaos caused by highway checks and other controls as local authorities attempt to prevent and control outbreaks.
