Not sure about YYZ, but in YYC there is a Customer Care Ambassador that checks to see if you have 'OSS' on your boarding pass. If you do, then you follow the OSS process. If you don't, then you follow the regular process. As well, there are passengers that are OSS eligible but then CBSA deems them ineligible (e.g.: transportation of firearms, importation of animals, dutiable items that require fee collection, etc.).
Why would someone not be eligible due to their origin airport? Wouldn't someone flying MEX-DEN-YYZ have gone through TSA screening in DEN and thus be just as compliant with Canada's security standards as someone who started in DEN?
And then couldn't someone starting in MEX and wanting to bypass an extra screening in YYZ just do MEX-DEN and DEN-YYZ as separate tickets so they'd get OSS?
