Perez won't ever give up trying to bring League to Canada. He's that passionate about it and has put in too much effort to give up now.
Ottawa, arguably, is in a better position than Toronto coming in the League anyway.
They have learnt a lot from Toronto's mistakes and have a better spread of investors, they hold an RFL license rather than being an 'invitational' side and arguably their biggest detractor, Elstone, is gone. They also seem to be taking a more measured approach with their spending.
I'm glad they haven't given up, although I'm certainly not confident of them taking the field in 2022.
With England making its antagonistic position on international expansion clear, first with the removal of Toronto and secondly with the promotion of Leigh over Toulouse, I think it's more important than ever that there is a long term roadmap for what they hope to achieve here. I would think the chances of multiple trans-atlantic teams, or a conference, ever coming to fruition are dazzlingly slim. That vision or direction is not present in England, at all.
Perez/Ottawa have multiple investors willing to put money into the sport, I want to suggest it might be better spent locally than trans-Atlantic. BUT the one, and probably only, thing England bring to the table, is high level talent and an established competition framework. The IP of most of the teams is internationally worthless. It would probably not be feasible to poach enough semi-pro talent and administration from England and Australia to fill even a small scale League One equivalent comp.
So where does that leave us...? 1 (maybe 2 if they ever find a way to revive the Wolfpack) Canadian team in the English comps to provide higher level representation and content. Build the local leagues until the quality of Canada League is roughly equivalent to League One. Then maybe one day you can pull Ottawa and its resources out of England and pour it back into Canada?
You could argue a similar pathway for France. If Elite One could grow and get funding to go full-time professional, even at a lower standard than Super League, you could mount a fair argument for Catalans and Toulouse to jump back to France.
