This section reads:
Where a person is, as a consequence of his conviction of an offence under this Chapter, deemed to be subject to a disqualification order, he shall be deemed to be so subject for a period of five years from the date of conviction or such other period as the court, on the application of the prosecutor and having regard to all the circumstances of the case, may order.
Essentially, it says that it is presumed to be five years if the disqualification arises from the commission of an offence. It would appear to me that this should be rather than as a consequence of his conviction of an offence under this Chapter simply as a consequence of this Chapter; in other words, all disqualifications should be presumed to be five years. If we were to delete the words "of his conviction of an offence under" that would carry a five year presumption in respect of all disqualifications which is more reasonable.
