Applying Study Visa while waiting for HSMP ? Help Needed

[Waseem]

Hi,
I am waseem from Pakistan. I had applied for HSMP in December 2006. According to the letter it would take 3 to 4 years to process. I want to apply for Study Visa in canada during this time. The course is related to my current job (Banker - ACCA). My elder brother and his family is also in canada.
What are my chances to get visa ?
What question i could be asked ?
Can anybody apply for study visa while waiting for HSMP ?
Having Elder brother in canada would have Positive or Negective effect on the process ?
