In a normal league the nation assigned to a team is useful when you select foreign limits and indicate to set them by team nationality and not the default league nationality. What you want to do is easy. Set the league nation to whatever nation you want and then go to the players tab. You'll have the option to change the country of origin for players that are created and one for players from the draft. There are two options because players are created in other ways besides the draft (free agents, etc). From there you can set whatever country you want and the percentage that the players should be distributed by (ex: 60% USA, 40% Canada). Actually I just re-read your post and what you want is for those teams to ONLY create players from their home country in a league (ex: usa team only creates Americans, canadian team only creates canadians). That's a bit more problematic. You can try and set the no foreign limits and set to team nationality but the AI isnt' quite as saavy with that and they tend to sign and release and sign and release players because of that limit.
