Toronto Wolfpack coach Brian McDermott insists the sport needs to start doing things differently in the northern hemisphere in order to grow.
The Canadian franchise will play in Super League for the first time this season after gaining two promotions in three years.
And the Wolfpack could soon be joined by fellow Canadian outfit Ottawa and American hopefuls New York in the Rugby Football League pyramid.
McDermott said: “I’m really excited to be part of a team that I believe could change the face of rugby league in the northern hemisphere.
“I think maybe another two teams added on the same lines of Toronto Wolfpack would change the whole game, which needs to change.
“Another 25 years of Super League doing what we’ve been doing is not the answer. I can’t tell you what the answer is but I can tell you what the answer isn’t and that’s repeatedly doing what we’ve been doing for the last 25 years.
“The responsibility of continuing this journey of making this game bigger than it’s ever been lies with us and maybe Catalans and maybe another that’s outside the UK.”
