A leaders' debate or presidential debate is a public debate held during a general election campaign, where the candidates expose their political opinions and public policy proposals, and criticism of them, to potential voters. They are normally broadcast live on radio, television and the Internet. The events may be organized by media corporations or non-government organizations.

Canadian leaders' debates are leaders' debates televised during federal elections in Canada, made up of two debates, one in French and one in English, usually held on back-to-back nights. The first time these debates were held was during the 1968 election. They were until recently produced by a consortium of the main Canadian television networks, namely the CBC/SRC, CTV, Global and TVA, although other channels such as CPAC carry the broadcasts as well.
