During elections, people often get a recorded message on their telephone that reminds them to vote and tells them where to go, to vote.
These messages, which use pre-recorded voices, are known as robo-calls.
Canada’s federal Conservative party is being accused of using robo-calls to mislead the public, during last year’s election.
The RCMP and Elections Canada (the group that makes the rules for elections), are looking into accusations that some robo-calls steered voters to the wrong polling station, or to polling stations that didn’t even exist, which would be illegal.
Prime Minister Stephen Harper says he doesn’t know anything about the illegal robo-calls.
