You can still apply even if you don't have the relevant work experience. But that's up to the university not to CIC to accept, if you get the offer of admission the only thing you have to show CIC is :
- Ties with your country in order to show them that you will return after you program is over (Real State, Family, Job Letters, etc), even if you want to stay in Canada after graduation.
- Proof of funds for you and your dependents for at least a year.
- Offer of admission to the University of your choice.
For the university you have to send them a strong Statement of Interest explaining them the reason of your choice of study field. Biotech is still related to IT, so all you have to do is to show them how it can relate to your case. You can send the same SOI to CIC as an additional document just for your peace of mind.
