[1] Graduating from Sheridan College, Milne debuted on the comics scene after being hired by Dreamwave Productions to pencil their Transformers: Energon series.

He would also work on Transformers Armada: More Than Meets the Eye, and the box art for the Alternators Jazz and Grimlock during his time there.

After the collapse of Dreamwave, Milne was hired by UDON to work on Devil's Due Publishing's third G.I.

Milne served as the primary artist alongside writer James Roberts for IDW Publishing's The Transformers: More Than Meets the Eye comic, which ran for 57 issues from January 2012 to September 2016.

Comic Book Resources disclosed that much of the work credited to Dreamwave founder Pat Lee was in fact drawn by Milne, who received only a fragment of Lee's payment for work on Cyber Force.
