The short answer is that all of the G7 countries have been hugely impacted by this pandemic. It has spared no country around the world.
Canada and the G7 countries in general are fortunate to be pretty rich countries and have the fiscal capacity to respond to help the most vulnerable. They have a history of credible, low, stable inflation and therefore have the ability to implement extraordinary monetary policies.
Sadly, many other countries around the world are not so fortunate, and their outcomes are considerably worse.
