求助：我姐去年底跟加拿大人结婚了，男方是永久居住权限

When someone gets married for the sole reason of immigrating to Canada, this is known as a marriage of convenience.
Under Canada’s immigration law, marriages of convenience are not allowed. Citizenship and Immigration Canada’s officers are specially trained to recognize genuine immigration applications, and they know how to detect marriages of convenience. They use a variety of techniques to uncover marriage fraud, including document checks, site visits and interviews with sponsors and applicants.
Canada’s immigration system is also set up in a way that discourages marriages of convenience. Anyone who wants to sponsor their spouse or partner to immigrate to Canada makes a serious legal commitment. As part of this commitment, sponsors must support their spouse or partner for three years, even if the relationship fails. If the couple breaks up and the sponsored person gets social assistance, the sponsor must pay back the amount of social assistance the former spouse received. Given the legal obligations, sponsorship should not be taken lightly, and everyone is responsible for ensuring that their marriage is genuine.
Citizenship and Immigration Canada recognizes that even genuine marriages can fail. However, if a person enters into a marriage of convenience and comes to Canada as an immigrant, enforcement action can be taken. This enforcement action could result in deportation, and is the responsibility of the Canada Border Services Agency.
