I believe in time President Obama will be regarded by the Latino population

Trudeau was the last in a line of highly transformative Canadian Prime Ministers of the 1950's-70's but also the most flamboyant and longest serving. He did a lot on his own, but also rode on the coattails of John Diefenbaker and Mike Pearson. These guys were generally recognized in their day for what they were doing.

Canada from it's ostensible independence in 1867 to the 1950's hadn't really changed a whole lot. It remained very much a British colony in a lot of ways, even if primarily psychologically and archaically conservative. These three Prime Ministers fundamentally re-imagined what Canadian society and it's relationship with the world should be in a relatively short time.

I think Obama will have a similar effect and recognized as either a one-off transformative President or the first in the line of them.
