Hi mohammad76, you have to write an email and ask them to re open your file containing reasons why do you think that they should look back into your case., i.e. degree of your wife. Don't mention the word "fake" in it but instead try and prove that when she studied, date, time , duration etc and explain other reasons why you think that they should look into your case. Also whatever you write, print that and post them the same thing or more as a registered delivery to their mailing address and wait for the outcome.
In the mean time, you may wish to write an email to Minister of Immigration and Citizenship Canada explaining the same.
