Gould's uncle was Donald Marshall Jr., whose wrongful conviction for murder occurred the day before Gould's birth: Gould's pregnant mother was so shocked by the verdict that she went into labor with him. Gould's first acting role was a minor part in the 1989 film adaptation of Michael Harris's 1986 book Justice Denied, which explored the events leading to Marshall's conviction.
Gould began performing professionally in Tomson Highway's theatrical troupe, Native Earth Performing Arts (to which Billy Merasty had referred him), and in Theatre New Brunswick; however, his career went on hiatus in 1992 when his parents were killed in a car accident.
Gould resumed performing in 1994, and has subsequently appeared in many Canadian television programs, including Blackstone, North of 60 and Cardinal, and films, including Rhymes for Young Ghouls and North Mountain.
In 2011, Gould won the Outstanding Performance Award at the Atlantic Film Festival for his role in the film Charlie Zone.
