There are certainly measures that could be taken in inspecting licensed establishments. We know that a number of those establishments employ people with no status in Canada, whether it be for adult dancing or massages. There is also the whole escort industry.
We have to have powers of inspection and increased powers over employment income, which is in provincial jurisdiction. Those tools allow us both to detect the crimes and to ensure that the employees are in good standing.
We must also remember that police services make considerable efforts to establish relationships of trust with various communities. The main obstacle to our investigations into crimes of this nature, especially human trafficking, is the mistrust that people from overseas have for Canadian police, which they often see as forces of repression. Police forces work hard on this. All the various community outreach programs and neighbourhood policing will help establish a level of trust, but that is a long-term process.
