Brison served as the Member of Parliament (MP) for the riding of Kings-Hants from the 1997 federal election until July 2000, then from November 2000 to February 2019.

[6][7] He attended Hants West Rural High School and then obtained a Bachelor of Commerce from Dalhousie University in Halifax.

[9] Brison was one of a handful of new PC "Young Turk" MPs (along with John Herron, André Bachand and Peter MacKay) who were considered the future youthful leadership material that would restore the ailing Tories to their glory days.

In July 2000, Brison resigned his seat so that PC leader Joe Clark could enter the House of Commons.

In the interim, Brison was appointed co-chair of the Tories' Election Policy Platform Committee, and became vice-president of investment banking at Yorkton Securities in Toronto.

In 2003, following Clark's retirement, Brison ran for the leadership of the Progressive Conservatives[12] on a platform of "new ideas", that consisted of Employment Insurance reform, more private involvement in health care, integrated defence strategy with the US, and socially liberal policies.

At the leadership convention, his campaign was dealt a crucial blow by John Herron who defected to the MacKay camp.

[citation needed] On December 13, 2003, he was appointed as a parliamentary secretary to the Prime Minister[15] with special emphasis on Canada-U.S. Relations and sworn into the Queen's Privy Council for Canada.

On November 4, 2015, he was appointed the Treasury Board President in Justin Trudeau's cabinet,[18] a position he held until the end of 2018.

In the summer of 2018, Brison initially committed to running in the 2019 federal election, however in December 2018 he decided to leave politics, around the time that he was linked to the controversy from the prosecution of Admiral Mark Norman.

[24] When Bob Rae dropped out on the third ballot and released his delegates, Scott Brison opted to support the politically similar Michael Ignatieff.

It was announced in October 2005 that he and his partner Maxime Saint-Pierre, an investment advisor with RBC Dominion Securities, intended to marry.
