When Harper announced that the retirement age was going to be 62 or 67 to receive the same amount of funds as those of 60 & 65 were receiving then, I know of at least 3 people who cheered upon hearing Trudeau cancelled that ruling. I am sure just a short question addressed to the government of Canada would bypass the need to research outside findings and you can even do that through Google and save a stamp.
Do charts proving that Harper was the worst Prime Minister Canada has ever had in all areas prove anything to you.

It's nice that you included this. I read it. The only thing I will say is that one report does not make your case. Economists or not, union interests are usually at odds with Conservative ideas on government. Several studies have to be presented before a proper conclusion can be drawn. At least you presented something. Most people around here don't, or use questionable sources.
Sadly, this doesn't count at all. The only thing that comes of these types of papers is ideological (Liberal vs. Conservative} thrust and parry.
These are some of the promises that the Liberals promised to do and that the J,Trudeau government kept.
