Nothing in the web site to suggest I go to the main Canadian customs hall.
Nothing to suggest I will get OSS - and even if I do, probably no impact on process coming from international arrivals to US departures.
Of course, with the semi-airside way to connect to US preclearance - no nexus available for security; nexus is available for US customs process.
