When entering the United States they also take fingerprints and a picture of your face.

That was the main reason why Europeans were forced to switch to a passport with biometric data (some fingerprints and photo) on a chip more than a decade ago.

Canadians don’t have their finger prints taken when entering USA

Fingerprints? I haven't ever had that happen. Perhaps only certain countries?

[iamjackg]

People from (all?) visa waiver countries have their fingerprints taken when entering the US, in addition to having to submit an ESTA[0] application before arrival. Last I checked, it still asked for all your social media handles (although you're not required to provide them).

I've seen it while returning from a trip to Taiwan recently, via JFK. They took fingerprints from non-US passport holders at Customs, I think; they didn't take mine.

I am a US resident alien (green card holder) and I have my fingerprints and picture taken each time I enter the United States.

...unless you're a US citizen, correct?

Correct.
