加拿大公民去美国读书入境时须带什么材料？

According to the manual from Canadian Department of foreign Affaris, we should have:

• documentary evidence of
sufficient funds to cover travel,
tuition and living expenses in
the United States;
• evidence that the applicant has
a residence outside the United
States and has no intention of
abandoning it; and
• evidence of scholastic and linguistic
proficiency for the academic
programs to be undertaken in the United States.

What about the evidence of residence out of the United States. I am now a single and renting a room from others, without my own residence. How to show I have a residence in Canada?
