Automated dialer supposedly doing a survey for the upcoming by-election in Winnipeg's River Heights ward: press 1 if you plan to vote for John Orlikow, 2 for Geoff Currier, 3 if you're undecided.
Since the pollster is unknown, you have no way of knowing where your information is going. Maybe it's genuinely an attempt at polling on the cheap. Or maybe it's one of the candidates' ways of creating a database of identifying which households should be reminded to get out to vote on election day, and which ones contain undecided voters.
Recommendation: No matter how you're planning to vote, press "3" to be recorded as an undecided voter.
