Threat Signal arose from the filthy, industrialized east end of Hamilton Ontario Canada in late 2003. A detuned, syncopated, melodic metal machine, Threat Signal combines the complexity of thrash metal, with a more contemporary groove sound involving technical rhythms, and melodic musical passages.

Before the band had played a single live show, their home recordings generated a significant interest online. The song ‘Rational Eyes’ hit #1 on the international independent music website GarageBand.com and remained in the top position for over 2 years. This prompted many record labels to take notice. One label in particular fit perfectly with the bands vision, and in 2005 Threat Signal inked a deal with Nuclear Blast Records.

Threat Signal’s debut album "Under Reprisal" was recorded with producer Christian Olde Wolbers (Fear Factory/Arkaea). "Its without a doubt my favorite album of 2006", Wolbers remarks, "A mix of Strapping Young Lad, Fear Factory, Soilwork… a true Canadian phenomenon!". Veteran mixer Tue Madsen added the final touches to the album and it was released internationally in August 2006. Embraced by fans and critics, perhaps the most meaningful praise for the album came in the form of the Canadian Recording of the Year award bestowed upon the band in their hometown at the 2006 Hamilton Music Awards.

After supporting "Under Reprisal" on the road for over 2 years, Threat Signal entered the studio in November 2008. They recorded their second album "Vigilance" with vocalist/producer Jon Howard (Threat Signal/Arkaea). Fellow Canadian Greg Reely was chosen to mix and master the album and it was released under Nuclear Blast Records September 8th 2009.

The third, self-titled Threat Signal album was released under Nuclear Blast records in October 2011. Recorded and produced at Planet Z studios by metal mastermind Zeuss (Chimaira, Hatebreed, All That Remains, The Acacia Strain, Born Of Osiris, Shadows Fall, Agnostic Front, Arsis). Artwork was created by Colin Marks (Origin, Scar Symmetry, Suicide Ssilence, Exodus).

The fourth album "Disconnect" is set to be released under Agonia Records early 2016. Recorded and produced by Jon Howard and Travis Montgomery of Threat Signal, Mixed and Master by Mark Lewis (Coal Chamber, Devil Driver, Whitechapel, Battlecross, Unearth, Bury Your Dead). Artwork for the album is created by Ludovic Cordelieres of Rusalkadesign.

Threat Signal has performed live with Soilwork, All That Remains, Opeth, Hatebreed, Children Of Bodom, Chimaira, Darkest Hour, Mnemic, Protest The Hero, Testament, Saxon, Nevermore, Lordi, Motorhead, Hammerfall, Arch Enemy, The Dillanger Escape Plan, Epica, Eluvitie, Scar Symmetry, The Browning, Kataklysm, and many more…
