Answer: The percentage of Canadian Hockey players in the NHL is currently slightly less than 50, as it was in 2016, while in the 1980s it was 75 percent. The National Hockey League evolved from a mono-ethnic and primarily Canadian professional athletic league to span North America and began its expansion of player nationalities in the 1970s.
