Sure, in particular it's around the Citizenship Act. Until 1947, for instance, Chinese were not allowed to become citizens of Canada. There are many different ways in which we exclude individuals from citizenship based on race, particularly during those days.
In my comment, I talk about the various ways in which this particular bill would result in the exclusion of certain groups. Live-in caregivers are in one group, and people from certain countries where English is not their first language are in another.
All those provisions added together mean that certain groups, because of their gender or their race, will be disproportionately affected by this particular bill. So while I am not suggesting in any way that this government intends to discriminate, we need to look at the result of passing this bill, which will mean that some groups are more likely to be excluded than others.
