the elder trudeau really turned a lot of things on their heads. he's maybe the only politician i'm aware of that would lie to conservatives, and then govern further left.

the best example of this is the wage + price controls fiasco in the mid 70s, coming out of the opec oil crisis and the resulting stagflation. the conservatives at the time were still old tories, so they were opposed to free trade and in favour of state intervention in the economy. a lot of voters were afraid that their income would be stunted if the government tried to enforce wage controls. so, trudeau campaigned against the conservative party's promise to bring in wage & price controls.

after he had won in large part due to his promise not to bring in wage & price controls, he brought in wage & price controls. like, the day after. with a zeal that made it clear he had balls out lied in your face about it.

that's just the most famous example...
