hi,
That means you are applying for student visa so it wont matter to your visa if you resign and apply ,,, it is just that if you are not sure of getting the visa then you may continue with your job.
the funds you posses is enough after depositing 10000 cad in gic and you would also hv to pay the fees of the course and it would approx cost you around 13-14k cad.
now you will have to appear for ielts, if not given yet, and if u hv the scores already then your admission and visa will depend on the marks....
