The actor was best known for his role as Finn Cotter on long-running family drama series Heartland. He sadly passed away on Friday in a hospital in Etobicoke, Ontario, after a serious fall.

"Robert was an athlete, an actor, and a great brother. He had a passion for helping others and was always looking to achieve more," his obituary read.
"He enjoyed movie nights with his family, and looked up greatly to his father. He impacted many people throughout his life whether it was family, teammates and friends."
It continued: "Rob's memory will live on through his passion for art and film; as well as his three sisters who meant the world to him."
