The OPC plays a number of roles. One of them is to investigate complaints and serve, as I said a few minutes ago, as an independent oversight to the government. The government has to comply with the law. It is assisted by the justice department, whose duty is to ensure that the government acts in accordance within the law, but all of these processes are within the executive branch.
One of the roles of the OPC is to provide confidence and trust to the population by having an independent look beyond the executive branch mechanisms to ensure that laws, and particularly privacy laws, are indeed being respected. It also has a proactive role.
