She later graduated from Bishop's University with a degree in Theatre Arts.

Mantel has been active in the entertainment industry since at least 1973 and has lent her voice to a wide array of animated projects.

Beyond these specific credits, Mantel's voice work is remarkably extensive. She has been a regular voice actress in English dubs of numerous international productions. Her filmography includes voice roles in series such as The World of David the Gnome, Bobobobs, Princess Sissi, Adventures of the Little Mermaid, Caillou, The Country Mouse and the City Mouse Adventures, Dragon Hunters, and many others. One of her most celebrated and long-running roles is that of Mrs. Sarah MacGrady (later known as Leah MacGrady) in the acclaimed children's series Arthur, a part she voiced throughout the show's run.
