Taggart was born in Toronto, Ontario, later growing up in Mansfield, Ontario [2] and has two brothers and one sister. Music was a central part of his youth, as his parents were also musicians, and Taggart learned to play drums at an early age. He has said the loss of R.J. Logan was a driving force to take his drumming to the next level. He auditioned for the then up-and-coming Our Lady Peace in April 1993.

In 1993, Jim Newell, Our Lady Peace’s previous drummer, left the band due to commitment issues. The remaining members and their management held open auditions for his replacement. They auditioned over a hundred drummers, ultimately choosing Taggart, who was 17 at the time.

In 2013, Taggart, who grew up in nearby Mansfield, emceed an event in Melanchton, Ontario celebrating the decision by The Highland Companies to withdraw its license to start mining in the area for limestone . He became involved in stopping the mine when a childhood friend alerted him about the issue.

In June 2014, Taggart announced that he had left Our Lady Peace.

In October 2017, Taggart and Torrens released the paperback book Canadianity: Tales From The True North Strong And Freezing, “a collection of showbiz tales from the road and relatable everyday anecdotes, all wrapped up in a nostalgic fondness for this great country. Canadianity takes readers on a cross-country journey, shining the spotlight on notable local heroes (or bahds), the best places to crush food and the greasiest watering holes, coast to coast to coast.”
