No need to compare what is needed to access to screening lanes in both countries; policies are different and rightly so.

The discussion, as you stated, is what happens after security screening and access to CBP. In YUL, the GE kiosks accessible without having to show TTP card. That doesn’t appear to be the case at YUL.

Correct. While there have been a few reports of people talking their way into PreCheck lanes using their GE card that’s not the program or the norm.

Speaking of no need to compare, we have an example of just that in the last sentence above. :D I think you meant to compare the use of a TTP card at YYZ to what is asked for at YUL with regard to a TTP. Or was I mistaken?

Indeed, the use of a GE card does not guarantee access to a present PreCheck lane and the allowance to be screened at the screening checkpoint like those who have PreCheck boarding passes.

I've never received my card, though I've asked repeatedly. Fortunately, I'm not planning to return to Canada any time soon.

Is the GE/NEXUS card REQUIRED when entering the NEXUS/Global Entry lanes in US bound land crossings from Canada?

Three situations:

1. US Citizen GE member--was issued a Global Entry card, but forgot it at home, but has their passport book on them, which is registered under Global Entry
2. Canadian citizen NEXUS member--was issued a NEXUS card, but forgot it at home, but has their passport book on them, which is registered under Global Entry.
3. Indian citizen, visitor to the US, not a US resident but is a Global Entry member (Indians have been eligible for GE since July 2017)--was NOT issued a card (as CBP does not issue GE cards to non-US residents), but has their passport book, which is registered under Global Entry.

In these situations, can these passengers use the NEXUS/Global Entry lanes when entering the US? FAQs and documentations are unclear as to whether the RFID card is specifically required for land crossings, or if a registered passport is sufficient.

All occupants using NEXUS lanes at land crossing coming into US from Canada must have a Trusted Traveler RFID card in their possession.
A NEXUS card is necessary to raise the barrier at Whirlpool Bridge port of entry entering into US.
All occupants using ReadyLane require RFID cards in their possession.

Driver and Trusted Travelers may be subject to expulsion from program for using dedicated land crossing lanes without appropriate RFID card.

I'm seeing posts about YYZ T1 requiring a GE card to obtain access to the machines. Is this the case for T3 as well?

Flying out of T3 soon as a UK citizen GE holder, so no card issued.

I didn't have anybody blocking the way when I went through T3 of YYZ like at terminal 1 (where they stood in front of the end of the security checkpoint before the GE machines demanding to see GE/NEXUS cards). I only flew through YYZ T3 once though (YYZ T1 on many occasions).

If you're not eligible for a GE card you might want to print out your TTP profile while logged into the DHS site showing you have GE and explain that non-US/Canadian citizens with GE don't get the cards if stopped..

When to Use Global Entry Card?
 

My understanding the GE card can be used in Canada preclearance airports on flights into the US. Having just arrived into YYZ and connecting onward to the US, I had to used the kiosk, just like arriving into other US airports on INTL flights.

Did I miss the opportunity to use my GE card? Did I carry it with me for no reasons?

No, the Global Entry card is needed for the Canadian version of the Pre-Check lane to get through security. (Although, when I was doing Preclearance at YYZ one time, they wanted to see my GE card before they'd let me to the GE kiosks.)

1) Using the NEXUS lane when entering the US by car.
2) At the TSA ID checkpoint at any US airport.
3) To access the CATSA "NEXUS security" lanes at Canadian airports for intra-Canadian flights.
4) To show the line dragons at YYZ that you are entitled to use the Global Entry kiosks. (This is the one that should not be necessary but can be.)

And importantly, in NEXUS or SENTRI lanes by foot. Saved me hours entering from Mexico.

Just tried to use the Global Entry lane at YYZ in terminal 3 and they wouldn't let me through. I lightly argued with the lady and the Canadian border officer that the machines do not take the card and the website specifically says I don't need it. They didn't care. When I did make it to the GE kiosk and to the CBP officer I asked him about it, and he says it's true I don't need it, but ultimately its their airport and he cannot change their policy. I'm just going to carry the card with me from now on.
