Canada isn't mentioned even once in the linked article, so you'll need to look elsewhere for data relating to this specifically.

Quick peek from the biggest performance data related to national covid response, comparing USA and Canada for total cases/population, and deaths/population, USA was about 300% more severe in both metrics. So, it's likely the immediate effects on life expectancy follow that comparative trend.

here's the latest figures from statcan that I could find (2021 data may not yet be available), specifically relating to life expectancy impacts: https://www150.statcan.gc.ca/n1/pub/91f0015m/91f0015m2021002-eng.htm
