Extension of stay as a student and applying for an student-related work permit.

[ked]

Hi, I been here in canada as a student for nearly one year and now i need to renew my student permit for one year more and also apply for an off-campus work permit. My question is: How much fees should i pay for my extension as a student and the off-campus work permit? I also have a dependent (Spouse) who is on an open work permit which he'll need to extend it as well. Can we apply both at the same time and in one application form only or separate ones? Please advise, thanks x
