IRCC will launch a new online portal for you to submit your application. The portal will contain a “How to Apply Tool” to help you decide which stream to apply under. There will be a wizard to assess eligibility, which you can skip. You will have to agree to some terms and conditions. Then you can create an account with your email address and a password. You will get a message sent to the email address you provided with a verification code, which you can copy and paste. After that, you will sign in with your email address and password.
