you can add your spouse without an ITA or even after submitting your application, adding spouse can increase the processing time as she would also need to get her medicals done, security and eligibility.One other thing I forgot to ask suppose if the CIC rejects our case due to incomplete information.Can we create a new Express entry profile and ask Ontario to link their nomination certificate to our new express entry profile so that we can correct the mistake and get out invitation again
why do you have to wait for the application to get rejected, submit it correctly at the first place and if you think you need time then don't accept the ITA.
