What is the test for a motion to stay a date for a civil jury trial in a motor vehicle accident in Ottawa?

The accident in this case occurred over seven years ago. There was no indication when a civil jury trial might be held in Ottawa at the time of the motion. Accordingly, the motion judge found that “the real and substantial prejudice arises simply by reason of delay”: at para. 46. I agree with the statement of Brown J.A. in his decision on the stay motion that this was a legally permissible finding and that “delay in obtaining a date for a civil jury trial can, by itself, constitute prejudice and justify striking out a jury notice.” As Brown J.A. notes, the whole raison d’être of the civil justice system, as captured in r. 1.04(1), is that courts will work to provide the “most expeditious…determination of every civil proceeding on its merits:” Louis v. Poitras, 2020 ONCA 815, at para. 33.
