Multiple Great Powers or Superpowers of North America

What are likely ways for two or three Great Powers or Superpowers to arise from the three major nations of North America? A limitation I'm placing on this is that Canada, Mexico, and the USA must all remain in existance, and none being weaker than they are in the present day.
 
Are modern borders required? If not, if Mexico wins the Mexican-American war and retains all the territory it historically lost, that maybe it could be a contender if they can industrialize. Of course, all the gold from California would help. This affects the western settlement in the U.S.A. , but the rate of immigration to the U.S. would likely remain the same, which could lead to some larger cities emerging in the west sooner as people had less room to expand (or less people moving west as the historically people just skipped over the great plains region and west straight for the west coast mainly.) Canada is tougher one. In OTL Canada proved to be quite capable of defending itself, but the its main obsticle to becoming a great power is its, relatively, low population (modern Canada's population is one tenth of the U.S.A.'s). Hope this makes sense as I'm not really an expert on the era I just talked about. Of course, other POD's are possible.

For Mexico a 1800s POD would be more helpful, since if it could win the revolution a bit less badly it would have the potential to industrialize. A lot of its already small middle class either died or emigrated, its industry and mining was pretty much destroyed, etc.
 
Mexico a super power? Itd need a POD a bit earlier then the 1800s, the revolution destroyed Mexico. Mexico would need much help from European goverments or the US herself to even compete. IF the 3 countries were superpowers theyd destroy themselves all anyways. I can see Mexico and Canda tearing the USA apart on multiple fronts

Er... The mexican war of independence started in 1810.
 
JTBC -- does the OP forbid the CSA winning the ACW, if the US continues in the north and is as "strong" as OTL? (Granted I don't think it that plausible, but that doesn't seem to stop it from being an AH staple :rolleyes:)
 
Maybe if Iturbide's empire survives, it could butterfly away the century of internal civil wars AND foreign interventions.
