Canadian vs US taxes

I have a similar question except I have a green card, am a Cdn citizen. Moved to the US with my wife and Son. My wife is a US Citizen.
But I work in Canada and cross the border every day, I have been paying Canadian taxes all along. Am I required to pay US taxes?

I am not sure when we will return, but i believe one day maybe in the Future.

All my banking and RRSP's are Canadian even my credit cards.

Please advise.

forums.serbinski.com is the place for these q's.

But I will tell you taht you MUST file a US tx return, reporting world income, becuase of your GC. You should only be paying tax in canada on your wages.

I wanna know ,too!
