Why would I declare items that are permissible? Pizza most likely is not permissible but chocolate, candies, etc are

That's not how it works. They ask you to declare food. Which chocolate is. Then they decide what's permissible.

YUL OSS - kudos
 

Do I like it! 15 min. from touching the gate to DOM MLL^

Yup, this. Yes to food. Tell the person what the food is. They update the computer, write on your Nexus slip and off you go.

Regardless if food is allowed or not, I would always click yes. Not worth loosing Nexus over something simple

Recently used 'OSS' connecting US > Intl at YVR. There is no separation on the arrival hallway, after deplaning, for OSS eligible flights. If they are saying passengers from non-OSS eligible flights need to be re-screened prior to boarding their connecting flight, what prevents them from handing off their bags to OSS eligible passengers during the walk down the arrival hallway, before the security checkpoint?

I've only experienced Germany's and Switzerland's version of OSS - and there is physical separation between passengers arriving from "OSS" eligible flights - i.e. they are directed to different arrival hallways/levels.

I expect there eventually will be (~5 years from now), but someone's assessed the risk and given them leniency in the meantime to use a makeshift solution.

Who are they? On the declaration card, it is specified the food categories that must be declared, it does not say food. I am referring to CBSA.

On the E311 declaration card it asks for "plants and animals or their parts/products". Does animal and plant products not include food for you? What is the food you eat based on?

Quite obviously chocolate is a plant product, so it has to be declared.

Quick question. If the line is really long for OSS and I go the traditional way for Nexus, does it matter if I have a checked bag? The bag will still be transferred directly US-->Domestic so will anyone bat an eye if I leave airside without my bags? Or is the no-pickup checked bag scheme a separate program? I'm talking about YYZ here.

No problem, it will not make a difference. The bag will still be transferred.

Much appreciated. Thanks!

The bags are always transferred regardless. It's part of the OSS initiative even though the bag transfer has been standard in Europe since before OSS. For some reason Canadian airports were traditionally not equipped to automatically screen arriving bags for transfer to domestic; with OSS that's redundant now as the bag screening done in the US or Europe is accepted. If Canada now did the customs at the final airport of destination with a red/green channel system, that would be awesome.

New to all this. Nexus holder flying DTW-YYZ-YHZ tomorrow. So if I understand this right (I have OSS on boarding pass) - I get off plane at DTW, and if the OSS line is long, its better to just go through Nexus and enter/-re-enter security then waiting in line and going on the bus?

Off the bus at YYZ? Yeah, it is an option. Personally, I've not had an issue with really long OSS lines, well, ever. Not in the last year, anyway. Unless you are right behind a 777 landing, even if you are in the back row of the wing'd bus form Detroit, you should just hang out upstairs.

It's been a long time since I've flown via YVR but today I'll be flying NRT-YVR-YEG. Does YVR have OSS? Debating whether to check my bag or not. If I check a bag would I have to reclaim in YVR?
