The federal government will launch an ad campaign that will set out to warn Canadians on how to protect themselves against marriage fraud.

Citizenship and Immigration Canada will post a seven minute long video on the department's website, featuring three Canadians who were the victims of marriage fraud.

The video along with three television commercials is the focus of the department's fraud prevention month.

A new law passed last year now requires sponsored spouses to be married for two years before they can get their permanent resident status. If they leave the marriage before that time, they face deportation. They are also not allowed to sponsor a new spouse for five years.
