Q: I am 17 years old and have several years of experience as a bike mechanic. I'd like to work for the summer and would like to understand process. I am a US citizen and would require housing.
A: See the attached link - it's to the Customs and Immigration Canada (CIC) website. Specifically, it's for those who want to work in Canada and are not Canadian citizens. Bottom line - you need a job offer BEFORE you attempt to cross the border to be able to obtain a work visa.
