Hello,
From what I understand, you want to apply right away for the CSQ (to get in the 5000 applications pool), but you are not married yet.
If you are already living for more than one year with your spouse, you already include her in your application as a common law partner (conjoint de fait).
If not, you can still apply only by yourself. However, after you have submitted the application, you will have add your spouse to your application. It is possible to do it, even after you will receive your CSQ. The immigration agent will simply reconsider your application in addition of your future spouse, ask the payment of applicable fees, make her sign the mandatory declaration of financial capacity, etc.
Regards,
