University of Torronto and other top colleges for MS in ComputerScience in Canada.

Can someone please throw some light on what is the major advantage or disadvantage of studying in Canada rather than USA(Msc in Computer science).Can one get a job in USA just after completing MS in University of torrento or any other college in canada. I would like to know the job opportunities for people who did their masters in Canada?(Again I meant jobs in Amazon,facebook,google,intel etc.)
