I would have been more inclined to give you a quick “yes” a year and a half ago, before I was in this job. Honestly, Ms. Rempel Garner, I've now met a significant number of refugees and asylum seekers. I haven't met a person who told me that their motivation was processing times. It's been fleeing challenging circumstances in every instance.
Conceptually, I can see why the argument suggests it could. Anecdotally, I've yet to meet a person who has indicated that was a motivating factor.
