Section 516 of the Criminal Code allows for an adjournment in certain circumstances. It's possible that the crown could apply to remand the accused for a set period of time so that the record could be obtained. That's one possibility.
In my experience, and I travelled to Williams Lake and worked in Prince George, the CPIC record was readily obtainable. I don't recall any instances where it couldn't be produced. I'm not sure how possible it is that there would be a circumstance where the CPIC is not available. It is up to an accused person to determine when they are going to ask for a show-cause hearing or apply for judicial interim release.
