Who can vote?
Well, if you are a Canadian citizen, and will be 18 or older on polling day, warm those pencils up because you are eligible. That makes you an elector. There are some exceptions, like if you are the Chief Electoral Officer of Canada, the Assistant Chief Electoral officer (since these positions are responsible for ensuring the accuracy and legitimacy of the election, he/she needs to remain neutral and therefore must give up the right to vote) or if you are in a correctional institution (jail) serving a sentence of 2 years or more. If you are serving a prison sentence of less than two years in a correctional institution, you have the right to vote in federal elections and referendums.
