Its mission is "to foster amongst the youth of Manitoba an understanding of, interest in, and engagement with the Canadian democratic parliamentary process that would enable their active participation in society as responsible citizens.

YPM's flagship event is Session, an annual model parliament that takes place from December 26 to 31 each year at the Manitoba Legislature open to all Manitoban youth aged 16 to 20.

[4] Throughout the week, members also have the opportunity to meet current and former politicians from the Manitoba Legislature and the House of Commons, partake in workshops, and socialize with fellow youth from across the province.

Recent keynote speakers have included Dr. Annette Trimbee, Susan Thompson, Senator Marilou McPhedran, Dr. Aimée Craft, and Wab Kinew.

Although each of these Parliaments has a unique style and emphasis, all are based on the same basic principle of fostering knowledge of the parliamentary system amongst Canadian youth.

The movement's goal was to foster the development of the physical, mental, spiritual and social well-being of the person as inspired by the biblical passage Luke 2:52, which reads: “And Jesus increased in wisdom and in years, and in divine and human favour.” YPs, only one of many TUXIS activities, were designed for religious as well as parliamentary training.

In 1960, “TUXIS” was dropped from the name, leaving “Older Boys’ Parliament.” In 1968, it was decided that YPM would expand its focus by becoming open to youth from non-Protestant backgrounds, thereby becoming non-denominational.

Two years later, the Western Canada Youth Parliament (WCYP) was officially formed, with its second session being hosted again in Winnipeg in the chambers of City Council.

The positions on the board are: The Cabinet is YPM's volunteer organizing committee, appointed by the Executive from the members (attendees) of the previous Session.
