Some student from ASU took the time to research how all US arenas and stadiums for the four major sports were funded. Seems like the trend is for increased private money for newer stadiums.

Is that true in Canada? Rogers, BC Place reno, Mosaic, BMO are all major publicly funded projects I believe. The economics for most Canadian pro sports aren't there to support the private money you see in the US.
