In the 1960s, Hans began wrestling and emigrated from his hometown in Punjab to Canada, arriving with $6 in his pocket. Hans trained in Toronto under Fred Atkins and eventually signed with Frank Tunney, a Toronto wrestling promoter. Atkins dubbed Hans "Tiger" after witnessing his ferocious style of fighting. Tiger made his Maple Leaf Gardens debut in 1965, wrestling as a heel. His first main event in Toronto was a tag team match late that year, teaming with Professor Hiro to take on the team of Johnny Powers and Sweet Daddy Siki. He began teaming with Fred Atkins in 1966. They became the top team in Toronto by defeating Whipper Billy Watson and Bulldog Brower for the international tag title in July 1966. Singh and Atkins wrestled at or near the top of the card through 1966 and 1967.
