You are not correct, MorehamEddy. 61% of Canadians did not vote against Justin Trudeau.

A ballot gives us an opportunity to vote for someone, not against. A ballot can only tell us who a person votes for.

Whether we vote against someone requires more analysis that simply counting votes, a little more polling and research. Do you remember, in 2015, when polsters asked people about second preferences? The evidence from that polling was that a high percentage of people who were going to vote NDP, Green, or Liberal, could easily vote for either of  the other two if it meant unseating the Conservatives. A much, much lower percentage of them would vote for the Conservatives as a second choice. Analysts also tended to agree that a high percentage of those voting Conservative would, as a second choice, simply not vote at all.

Therefore, with Liberals getting over 39% and the NDP nearly 20% and the Greens over 3%, it's clearly the Conservatives that most Canadians voted against.
