Most likely. I've been traveling to/from Canada 3-4 times a month for the past decade and about every 18-24 Months I get this. When I check in at the airport, the kiosk will request that i scan my passport. After that I'm good. It always seems to happen when I'm returning from Canada, never had it happen on an outboard journey.
