In Canadian politics, a Ten Percenter is a party political flyer that MPs have the right to mail — at no cost to themselves — to households in their own ridings, equivalent to 10% of the households in their constituency. They may also send the same flier to all of their constituents if they change 50% of the copy.

Prior to March 2010, MPs were allowed to send ten percenters into their opponents' ridings. A motion by Michael Ignatieff to have the practice disallowed passed by a slim majority. There was a minority government at the time. Conservatives voted overwhelmingly against this motion and vowed to ignore it. In 2010 the practice of sending tax payer funded propaganda into their opponents riding was banned by the House of Commons Board of Internal Economy.

In 2008 and 2009, most Yukoners received what was essentially the same flier except for a small block of very tiny copy in one corner of each rider. This was how Conservative politicians were able to get around the 10% rule.

While ten percenters are in theory supposed "to keep Canadians informed on the important activities undertaken on their behalf by their elected representatives" Ten Percenters are sometimes viewed as controversial, because public money is used to promote the MP's political party.
