As per CIC is concern you need to provide PCC if you live in a country for continuous 6 months & if you are 18 years or older at that time. So if your wife had stayed for continuous 6 months then YES otherwise NO. Below is the reference from CIC website......
Police certificates
All applicants must submit police certificates/clearances as part of the application process.
You and all of your family members who are 18 years of age and older and who are not already permanent residents or Canadian citizens will have to provide:
a valid police certificate, or
police clearance, or
record of no information.
These documents are to be provided for each country other than Canada, in which you have lived for six consecutive months or longer since reaching the age of 18.
Note: If you or your family members were under 18 years of age (16 years of age in certain jurisdictions) for the entire time you lived in a particular country, you do not need to provide a police certificate for that country.
Before submitting your application to the CIO, you should:
research the estimated length of time required to obtain police certificates from all of the applicable jurisdictions, and
begin to gather your police certificates.
Note. We strongly recommend that you submit your police certificates with your application to the CIO. If you are unable to obtain all the necessary police certificates, you may still send your application to the CIO without them. However, please note that if your application is placed into processing you must be ready to submit them to the visa office when requested.
Note: If you are including your police certificates with your application to the CIO, please ensure that your certificates were not issued more than three months earlier. Police certificates are generally valid for 12 months from the date they are issued. However, if a final decision is not made on your application before the expiry of your police certificate, the visa office may request that you provide a new one.
If a certificate is not in English or French, submit both the certificate and the original copy of a translation prepared by an accredited translator.
Unless otherwise specified on our website, it is your responsibility to contact the police or relevant authorities unless otherwise specified on our website. When doing so, you may have to:
pay a fee for the service, and
provide information or documentation such as:
photographs,
fingerprints,
your addresses and periods of residence in the country or territory.
CIC will also do background checks to determine if there are grounds upon which you and your family members may be inadmissible to Canada.
) and i had assumed that my application will get rejected. i tried to reach out to CIC by phone and email but there is no way to do so till you get your UCI number. I quickly went ahead an increase the international transaction limit on my CC and prayed to god that CIC tries CC transaction atleast once.
