This 'article' (its a blog post if anything) is based on this this CBC article.

https://www.cbc.ca/news/canada/edmonton/fires-set-by-firefig...

The article refers to a report that 404s.

Both the OPs post and the CBC article say records aren't detailed for this so unless theres some studies (lol funding in current political era) you prob will never have real percents.

But i think its fair to say yea firefighters are more likely to be arsonists i guess.
