you can apply for a visitor visa for your wife, but it's quite likely to be denied. CIC in general doesn't grant visitor visa to spouses, because they are afraid that your spouse won't leave the country at the expiry date, and overstay.
However, you can always try and if she gets denied, it won't have any bearing on your application. Try and include as many proofs as possible that she will be returning to India after her visit to Canada.
Good luck,
