"Come on, chop-chop, we're late!".
It was 8:40pm, Saturday before last, we were on our way to an advance polling station. Although the official voting day for Canadian federal election was April 28th, we hate the long lineup on the voting day so much that we always vote in advance.
The official results were out yesterday. Surprise surprise, the Liberal party didn't hit a home run, but made it to 3rd base: they won 168 seats in House of Commons, just 4 seats short from a majority government.
By looking at the CBC projection polling chart below, you will know what the surprise was. 
BTW, I didn't vote because I like any particular political party, I voted for Canada. By the election results, I think many Canadians felt and voted the same way.
Cheers!
