OTTAWA – A Quebec man is threatening to sue Immigration Minister Marc Miller because the federal department lost his Cuban wife and her son’s sponsorship application file that included copies of passports, tax filings and even birth certificates.

“These errors and boondoggles at Immigration, Refugees and Citizenship Canada are causing not only stress and anxiety to my clients but are also a waste of money, energy and time for Mr. (Yves) Charbonneau and his wife, Mrs. Vega Suarez. The couple lives separately while the sponsorship file is being processed,” reads a letter of demand sent to Miller by lawyer Stéphane Handfield.
