What I need to travel to Canada if I am on a Us work and travel visa ?

I would like to see Niagara Falls from the Canadian side. I am on a Us work and travel visa that will expire in october. I want just to pass the border Us/ Canada with my friends (they all have a green card except me) and come back in Us in the same day. Do I need to aply for a tourist visa for Canada and then, the other questions is when I 'm coming back to Us I wont have problems with my visa ?

Your work and travel visa must be approved for Canada by the Canadian Consulate in the U.S.In addition,you will require your passport.Without your passport ,all the work and travel visas from around the globe will do you no good.

You can also verify by surfing on over to the Canadian Immigration Service web site where you will find definitive answers to your questions;or,contact the Canadian Consulate nearest you.You will find it in your phone book.

if you are not american i would get a visa and make sure you have your passport

I would recommend a visa. You can get over the border no problem, you will probably have a hard time getting back!
