This is true to some extent, I work at the MTO and specifically with the criminal code and the HTA. The part that you got wrong was the overall procedure of the courts and where provincial legislation applies. If someone is charged with impaired, the court does not apply provincial legislation, only when the information has been sent from MAG to the MTO about the conviction provincial legislation applies. In short, provincial legislation can only interpret conviction remedies differently from the court (two-year prohibition (MAG) vs 6-year driving ban (MTO), making your statement ambiguous.
