I am in the same boat - my common-law partner is a Canadian citizen already.
On the Express Entry Application (IE: what gets us entered into the pool) I chose:
-Marital Status -> Common-Law
-Number of Family Members -> 2 (her and I)
-Relatives in Canada -> Yes, Spouse/Partner
-Is your spouse/common-law partner included in this application? -> No
As a result I did not have to submit any language scores, education, etc. for her and my scores were applied as an individual. Makes sense, as others have pointed out.
Now I received an ITA and on the Permanent Residency Application and there is a section specifically for my spouse.
Interestingly, the first question in her "Personal Details" section is: "Will this person accompany 'the primary applicant' to Canada". It is already answered as "No" and to change it, one would need to modify family information as the help window says. Below the answer I am allowed to explain why she will not accompany me to Canada. I typed that it was because she is already a Citizen living in Canada. It is an oddly phrased question so I'm curious if anyone has a different take on it.
Anyhow, as part of her section of the application we must (just like the primary applicant) submit information on her immediate family, provide 10 years of addresses, 10 years of travel outside the home country, 10 years of personal activities, etc. This part is tedious but it gets worse.
Once you get past the survey part of the application you move onto the part of the application where you can submit all of your supporting documents. This is where things get weird for those of us with Canadian spouses.
My spouse again has her own section where it asks for her:
-Police Certificates
-Proof of Medical Exam
-Digital Photo
-Passport/Travel Documents
The police certificate and medical exam are not exactly easy or cheap. Is it right that we have to submit these for someone who is a Canadian citizen?
arleneramiro - you mentioned that the spouse wouldn't need a medical exam. Where did you get that information?
