Jean Chretien, Shawinigan scandal.

Brian Mulroney, Airbus scandal.

Oddly, I couldn't find a really big thing for Stephen Harper, but there are many lists of smaller things he did that are objectionable to one degree or another. My biggest gripe was him calling coalition governments undemocratic. When your whole philosophy goes against working with other groups to achieve the goals of the citizens that you believe the whole concept has to be wrong, it says more about you than the people you're complaining about.

Justin Trudeau had the lavalin scandal, as well as some very hypocritical situations in the first year of his leadership, as well as either botching or throwing the voting reform promise.

Pierre Poilievre has already gone on the record as intending to pass laws he knows are unconstitutional, and using the notwithstanding clause to keep them in force, which, while not illegal, I feel is deplorable, and he isn't even in power yet.

I miss the days when conservatives fought for freedom and not control. I'm willing to admit the difference may be my perception and not their intentions.
