Richard - after reading your previous post it is clear you need to talk to someone professional.
I suggest you contact CBSA and as PMM stated earlier, they are keen to discover the spouses who "disappear".
Phone 1-888-502-9060. This is the phone number for the Canadian Border Services Agency. The office is located in Ottawa. It is open 24 hours a day, 7 days a week. It is the main federal agency that enforces Canada's Immigration Act
You will hear a voice message system. Press "1" for service in English. You will hear another voice message which will give you a number of choices. If you press "1", you will get to speak to an agent. Please tell the agent what you want to report. If you prefer to leave a voice message, press "3". If you want to FAX information to CBSA, use the following number : 1-613-948-4848.
Give the agent as much specific information as possible. All information you give will be held confidential. According to the CBSA, the following are minimum requirements in the information you should give them: (a) the complete name(s) of the person or people committing the fraud; (b) the age or date of birth of the person. Please try to provide other important information such as the country of birth, home address, work location, etc.
When you speak to the CBSA, tell the agent the kind of fraud you believe has been committed i.e Foreign spouse deserting (soon after they get here) their Canadian spouses.
It is extremely important that you ask for a Log or Case Number. If you get more information and need to call again, you will need to give this number to the person you speak to. Getting a Log or case number will avoid the problem of repeating your information.
Here is the Canadian Border Services Agency web site address:
www.cbsa-asfc.gc.ca The Canadian Border Services Agency will begin an investigation. The length of an investigation varies.
Good luck. If this is a genuine fraud on your wife's part, please do not hope it will go away. You do need to do something.
