Travis Price started Pink Shirt Day about six years ago with a high school classmate when they bought pink shirts for students to wear in support of a new student who was bullied when he wore pink.
Their campaign led to the second Thursday of every school year being designated Stand Up Against Bullying Day in Nova Scotia, which encourages people to wear pink to school or work.
In announcing his candidacy, Price says he wants to try to make a difference in the legislature for children and families who have been the target of bullying.
Also running in the new riding of Fairview-Clayton Park are Liberal candidate Patricia Arab and New Democrat Abad Khan.
A date for the next provincial election has not been set, but the NDP is expected to call an election this year.
