West Coast singer-songwriter Shawn Hook is now in the running for a Juno Award, after organizers of Canada's most prominent popular music honour revealed an error with one of the previously named nominees.

The Canadian Academy of Recording Arts and Sciences has rescinded Nunavik pop singer Elisapie Isaac's Juno nomination in the breakthrough artist of the year category, due to a technicality.

In a statement, CARAS noted that the Quebec-based singer-songwriter, who performs as Elisapie, is ineligible for the category because she is a past Juno-winner, having won the 2005 Aboriginal recording of the year award as part of the duo Taima.

Only first-time Juno nominees can be contenders in the breakthrough category.

"It's very unfortunate that this situation occurred, and it in no way reflects on the authenticity of Elisapie's unique talent and artistry," CARAS president Melanie Berry said in the statement.

Isaac's slot has been filled by Shawn Hook, a singer-songwriter and musician originally from Nelson, B.C.

Songs from his May 2012 major label debut, Cosmonaut and the Girl, have been featured on TV's Touch, Degrassi: The Next Generation and Shameless, while he has toured with artists such as Emeli Sandé, Lights and The Midway State.

Hook's rivals for the breakthrough artist Juno include Cold Specks, Grimes, Kira Isabella and The Weeknd.

The 2013 Juno Awards take place in Regina on April 21.
