The government of Ontario releases the salaries of all public employees every year if they make over 100k. So called sunshine list https://www.ontario.ca/page/public-sector-salary-disclosure
I think this goes overboard: a min/mean/median/max for each job title would be good enough to know where I stand in a salary negotiation. I also like Ms. Zaloom's idea from the article to share salaries among close friends and family.
