When Andy Creeggan (who played congas) returned from a trip to South America to find Stewart on drums, he felt somewhat displaced.

Stewart is the only band member who has not actively written songs for the group's albums nor does he write for a side project.

[1] His stepfather sang in a Scarborough rock band named "The Wizards of Id", formed at Woburn Collegiate Institute where both Steven Page and Ed Robertson would later attend.

[2] He credits his parents' relative youth (they were only 19 when he was born) with exposing him to interesting music which was frequently played around the house when he was young.

When he met the Barenaked Ladies, at a buskers' festival, he was drumming for the Would Be Goods, a Guelph acoustic duo featuring stage actor Christine Brubaker, and singer Chris Reynolds.

He took part in Super Skate, a celebrity hockey game fundraiser at Madison Square Garden for the Christopher Reeve Foundation in 1999, 2001 and 2002.

Participants included Denis Leary, Kim Alexis, Rick Moranis, Chris Jericho, Gary Dell'Abate, Chad Smith, Darren Pang and Jason Priestley, among others.

[3] Stewart is the first cousin of Kevin Yarde, a former television presenter for The Weather Network and the current Member of Provincial Parliament for Brampton North in the Legislative Assembly of Ontario.

Previously, He had his own signature sticks made by Regal Tip from 2004–2015 which he designed with his drum tech, Rob "Tiny" Menegoni.
