We focus on immigration-related purposes. The customs and collections aspect of this bill is of less immediate or direct relevance to the immigration department.
First and foremost, I would say that the benefit of this bill will be to establish residency requirements and to document overstays. Temporary residents, for example, are normally not allowed to stay more than six months on a normal visa or eTA. If they overstay in Canada, we will be able to establish that.
I don't believe that the immigration department is best placed to answer tax questions.
