This practice is interesting on several levels. As indicated in the article, it would be interesting to note the racial or ethnic origins of the individuals having their status checked. It would not surprise anyone if most of the individuals having their status checked are visible minorities.
Constitutional questions also are engaged by this practice. For instance anyone being investigated must, at some point in the process, be advised of what they are being investigated for. Are Toronto police advising these individuals that in addition to whatever criminal matter they are being questioned about that they are also having their immigration status looked into? Is this even within the remit of the police? If not, should it be and be legislated as such?
Important legal and societal questions that beg explanation and clarification from the police and well as discussion and contemplation by the rest of us. Given the bright spotlight being placed on newcomers as security risks it is incumbent on the government to address this issue as the intersection here is very obvious.
