1. Malignant neoplasms (aka cancerous tumor) 82,412
2. Diseases of heart 57,357
3. COVID-19 19,716
4. Accidents (unintentional injuries) 18,365
Note: the list also has an "Other causes of death" at 78,354 but that's not one specific thing so can't be included in the ranking
Some age statistics regarding COVID deaths from their own analysis: https://www150.statcan.gc.ca/n1/daily-quotidien/231127/dq231...
> The proportion of COVID-19 deaths among older Canadians aged 65 years and older rose to 91.4% in 2022, approaching early pandemic levels. This increase was largely felt by seniors aged 80 years and older, who experienced a 78.2% increase in COVID-19 deaths from 2021 to 2022. In contrast, deaths due to COVID-19 decreased to 8.6% for those younger than 65 years in 2022.
So this is hitting 80+ people the hardest, then 65+... but under 65 has gone down.
