The only other thing I will add is: all authorities, including government departments and the police, simply need to follow the law and apply it fairly (meaning each citizen is equal). By and large both Canada and the US have pretty good laws. There are gaps and errors of various types and sizes, but if we take criminal codes, both countries would do well if the laws were simply applied as their statutes require.
Beyond that, it is reasonable to help those who are suffering (socially, economically, racially, whatever), as well as those who have suffered historically scaled injustices. It is straightforward that injury can be very difficult to overcome, especially if it has occurred over generations. This makes it reasonable to spend effort and money helping such people. It is rationally right as well as ethically.
(I can't respond to some of the misinformed ignorance of some of the posts. As for Spocket; well, its not even worth it - his/her information and opinions are just ignorant in the technical sense.)
