Bass player Andrew McCracken left to concentrate on his design company Doublenaut. His spot was filled in by Jason Bailey (former member of Figure Four and Shattered Realm) for most of 2007. However, Bailey was then replaced by Jaye R. Schwarzer (formerly of Left Behind, Hope to Die, Minesweeper, and Kover) as he wanted to focus on being a graphic designer; he still designs artworks for Cancer Bats and remains friends with Liam Cormier.  The band released their second studio album called Hail Destroyer on April 22, 2008. The album features guest vocals by Wade MacNeil of Alexisonfire and Black Lungs, Tim McIlrath of Rise Against and Ben Kowalewicz of Billy Talent. The release was held at the Mod Club in downtown Toronto with Liam Cormier not only singing for Cancer Bats, but also performing drums for Black Lungs. On May 17, 2008, Cancer Bats were put on the cover of Kerrang!, a publication which gave their album Hail Destroyer a KKKKK review (highest possible) as well as a 5k Live review on their headlining UK tour. Cancer Bats were also nominated for 2008 Album of the Year for the 2008 Kerrang! awards.  Cancer Bats have performed at the Download Festival in 2007, Groezrock 2007 and at both Reading and Leeds Festivals in 2007 and 2008. In the summer of 2008, the band did an extensive summer and autumn tour with Bullet for My Valentine, Black Tide and Bleeding Through, as part of the No Fear music tour across North America. Also in 2008, they were a support act for Welsh band Funeral for a Friend during their tour of Britain and northern Europe.
