Colonel Gibson, this is perhaps a technical point.
On the commencement of the sentence—I don't know if this changes anything—it says the “punishment of imprisonment or detention shall commence on the day on which” the sentence is pronounced. For instance, the fact that detention is supposed to take place in Edmonton, do we count the time to get there as part of the sentence? And with regard to “subsections (3) and 148(1)” and “sections 215 to 217”, what do they provide by way of exception?
