Where did you get this information? Is there anything else we can send via email?RajaJi said:CIC accepts following forms Signed and Scanned (and sent to CIC via email)
1. IMM 5476 (Use of Representative),
2. IMM 5744 (Consent for an Access to Information and Personal Information Request) http://www.cic.gc.ca/english/department/atip/requests-personal.asp
so I do not think it will be a problem with IMM 1344.
If you do not want to take any chance, sign the form and mail it via courier to your wife in Canada.
