Canvassing

Canvassing is when people go door-to-door in a neighborhood to talk to people. They usually talk to people to get their opinion on something or to get them to do something. For example, politicians might go door-to-door asking people who they're going to vote for in an election. Or a charity might go door-to-door asking people to make donations. Canvassing is just a way of talking to people in person.
