Hi Kavya,
As long as you can prove that you are going back after your school, VO will give you a student visa...in our case, mu husband applied for student visa with me and our 2 children and they still give us the visa without interview or additional requirements, we just showed that we still own a house in our country and our parents and siblings are all there, plus we explained in the statement of purpose that getting a good education in canada will help our country when we go back...
Also, please make sure to ask for the fees in the university, mostly the fees in the website is for canadians and it is normally double for international students...
I had a friend who applied after us and she applied with her husband too and they get the visa too...however, if it is really your intention not to bring your husband right away then apply for him later after you have landed here and settled...the only thing you have to consider is that no matter when your husband will apply his expiry will just be the same as yours...
For the univ, you can pay one yr fees first, then apart from your receipt of payment, you should still be able to show around $12 to 15k for the 2 of you and 10k if you're alone...
goodluck on your application
