International student re-enter Canada NEED suggestions

[andrew49]

Hi,
I am an exchange student (4 months) from Hong Kong, and I am not required to have both study permit and entry visa (TRV). As I have to attend an important interview next week, therefore, I have to return Hong Kong for 9days. I would like to ask whether I am able to re-enter Canada and what kind of documents I should have when I return to Canada?

Thanks!!!
