I had a similar situation as @akel , I had to travel for landing to Vancouver with expired VISA and valid i-94.
-For me the officer asked some basic questions and handed me a yellow paper and told me to go inside the office to get the paper work.
- I went inside and a different officer asked very basic questions about my work, where do I live in the USA, and etc.
- Then he stamped on a paper, stapled that to my passport and suggested to pay USD 6 to the counter
- I paid USD 6 and was out of the building in 10 minutes.
- The whole process was appx 15 minutes long
- Couple of days after this, I generated my i-94 online and I can see this entry and exit dates on the travel history
- Overall, the experience was pretty smooth and hassle-free
Regarding GTF, the officer on Canadian side did not even care to see a list which does not have any big value item. He mentioned that we don’t care so much about your personal electronics that don’t cost more than 5k-10k. We are only worried if you are bring new high-value gadgets. Personal use goods are fine. He was extremely helpful and added my car in the list (I forgot to add that) with valuation and stamped for future reference.
