I may or may not vote in the by-election to elect a new Member of Parliament. My MP resigned in May. The election date is not set but it should happen by the end of the year.
I didn't bother voting in the last federal election (last year). I voted in the three prior ones (2004, 2006, 2008). My political beliefs did not align with the ideologies of any of the political parties in the last election so I chose to withold voting for any of them. If I could express my dissatisfaction with all of the candidates by marking a "none of the above" on my ballot I'd be sure to vote every election.
