Should I get a US visa?
If you need or want to travel to the USA (for a vacation, to visit a friend, for work, or just transiting via a US airport on your way to somewhere else), then by all means go and get a visitor visa. If you dont need to travel to the USA, save your money and time and dont apply for the visa. As to whether you will get a visa if you apply, nobody can predict this. But my impression is that Canadian residents with more or less well established residential ties (a job or university enrollment in Canada, a rented or owned house or apartment) are usually treated reasonably well by US consulates.
