I contacted Elections Canada and they do provide names and physical addresses (but not 'phone numbers) for everyone on the voters' list to the candidates. These lists may then be used as a basis to look up telephone numbers in other, third-party databases. And then there's the huge loophole where our politicos exempted themselves from our country's joke of a do-not-call list.

Apparently the only way to be removed from lists provided to candidates (excuse me, my physical address is not public info... that's why I pay some ridiculous sum + HST for a PO Box) is to ask to be removed from the voters' list entirely, then request to be re-added at the last minute in order to vote, then ask to be removed again until the next election.

Impractical, and that still doesn't prevent candidates exploiting the do-not-call loophole to obtain residential numbers to use and abuse from other sources.
