Immigrants should adopt the values of the society they enter. Their willingness should be declared when they land.
If they cannot agree, or lie about their willingness to adopt the values of their new home, they should be subject to immediate deportation- regardless of country of origin or religion.

Canada has recently had the horrible case where a Muslim family was convicted of killing their daughters and the man's first wife because they would not conform to the strict values brought from their former society and adopted the freedoms of Canadian society; an "honour" killing.
The killers have been sentenced to life in prison. Unfortunately Canada has legislated against the death penalty.

Muslims- or any group- must not be tarred wholesale with the same brush. Canada has received many who have adopted Canadian values and are making a contribution to the country.
