Mike McKenna (born April 15, 1946) is a professional Canadian rock / blues guitarist[1] noted primarily for his electric slide playing.

Born in Toronto, Ontario, Canada, McKenna began playing professionally in the early 1960s in Yorkville where he formed the group Mike's Trio.

Unfortunately inconclusive contract negotiations and conflicting priorities, (including Rothchilds' bust on a possession charge) saw the band returning to Canada and eventually disbanding.

McKenna has been with a number of notable groups throughout the years since Mainline called it quits, including tenure with Downchild Blues Band, Diamondback, and The Guess Who (in an early 1980s post-Burton Cummings lineup).

When Toronto's internationally known El Mocambo Tavern closed down in November 2001, the alumni Mainline members (but without Joe Mendelson) were invited to perform and McKenna along with Tony Nolasco (drums, vocals), Ted Purdy (acoustic guitar, vocals), Mike Harrison (bass), and Bob Adams (harp) entered Toronto's rock history as the last band to grace the El Mo's famous upstairs stage.

The event featured a who's who of Toronto's rock and roll / blues / Yorkville Sound scene including the original members of Mainlne - Tony Nolasco, Mike Harrison, Ted Purdy (who replaced Mendelson) and Bob Adams (sitting in on harmonica); Luke Gibson (of Luke and the Apostles); Dave Bingham (of the Ugly Ducklings); Kensington Market; various members of DiamondBack; and Scott "Professor Piano" Cushnie, among others.
