Nova Scotia also saw a spate of excess deaths that remains unexplained.

What is contributing to the excess mortality rate?

Likely lockdowns.

Lockdowns have contributed to increased rates of obesity, decreased physical activity, missed doctor appointments, drug overdoses and suicide. https://t.co/sVq2JdQFYY

Tara Moriarty, the COVID-19 Resources Canada project head, funded by the Public Health Agency of Canada for its COVID modelling work, told CBC she worried vaccine skeptics would use the Nova Scotia data to come to conclusions other than her own

According to CBC:

Moriarty is calling on the province to explain what is behind the persistent, positive excess mortality numbers. She worries that without an explanation, purveyors of COVID-19 misinformation will argue that COVID-19 vaccines are to blame.

Sweden has pursued the most liberal strategy: Risk groups are protected, and people with flu symptoms stay home.

"If you follow these rules, no need for further measures, the effect of which is only marginal anyway,“ chief epidemiologist Anders Tegnell.https://t.co/pnK7tVksGZ

Countries that did not impose strict COVID lockdowns did not suffer excess deaths.
