Ottawa, Canada’s Enforcer is a traditional heavy metal band whose musical style embraces the catchy, melodic aspects of 1980s metal and fuses them with present-day power and aggression. The music features stellar songwriting, powerful, melodic vocals, blazing guitarwork, dynamic bass grooves, and intense yet intricate drumming. The band will appeal to fans of Iron Maiden, Judas Priest, Black Sabbath and many others.

Enforcer was formed in 1985 and has released several demos and played countless shows, including many at premier venues Roxannes and Barrymores, as well as prestigious slots opening for Warlock and Pat Travers among others.

Now, in 2019, Enforcer is BACK with a new lineup and is poised to strike! Coming soon – new studio material and live performances!



The band was formed by drummer / vocalist Pete MacCormack and guitarist “Metal” John Pottier in the Fall of 1985 in Ottawa, Canada. The band added 2nd guitarist Ron Proulx and bassist Remi Drouin in winter 1986 and a 4-song demo was released in May 1986. The band supported the demo with many shows in the Ottawa area including high-profile premier venues Roxannes and Barrymores. In 1987, with Pete deciding to focus on drumming, the band recruited lead vocalist Chris Lemyre. The band got back to work right away, and in 1988, released another demo before returning to tear up the live circuit – including playing prestigious opening slots for Warlock and Pat Travers among others! With drummer and founding member Pete MacCormack joining legendary Ottawa metallers Shock, the band disbanded in 1988.

Metal John teamed up with drummer Louis Clement and bassist Dan Lafleur in 1989, writing songs under the name Nil Obstat. With Mario Martin later taking over the drum throne and Remi Drouin returning on bass, along with lead vocalist John Jamael, Nil Obstat focused on the live stage and played many shows between 1990-1991.

In 1993, the Enforcer name was resuscitated, featuring a new line up with Kevin Spero on drums , Steve Carter on vocals, Remi Drouin on bass, and Dave Ray and Metal John on guitars. Another demo was recorded and the band continued to perform live.

In 1994 , the band split up and Metal John joined Peace Colony along with ex- Enforcer founder/drummer Pete MacCormack , Tony Ve ( Shock ), and Terry Mackay (Nefarious) . The band later changed its name to Think Tank. In March 2018 , Metal John and Louis Clement decided to re-ignite the Enforcer flame. Dan Lafleur (Second Sight, Transcendence) returned for bass duties in January 2019, and in February, the band joined forces with new lead vocalist John Perinbam (Ivory Knight).
