I had a question about the way deemed aquisition works for capital gains

Hey. I had a question about capital gains and the way they work. Note : I am neither a US resident or US citizen (which means I am not subject to exit taxes)

Lets say that I got 10 amazon shares vested at 150 dollars and I became a resident of Canada at a date at which

the share price (FMV) was 180 dollars. Lets say that now I sell my shares at 200 dollars. Now I want to understand my taxation liability here. As per deemed acquisition laws in Canada, I am only required to pay Canada taxes for the 10 * (200 - 180) part. However for the rest of the amount (i.e. 10 * (180 - 150)) part, I would have to pay taxes to the US correct? I cannot find anything in the IRS website that suggests I do. However, I presume I would have to pay taxes for it somewhere right?

According to the IRS here, "if your only U.S. business activity is trading in stocks, securities, or commodities (including hedging transactions) through a U.S. resident broker or other agent, you are NOT engaged in a trade or business in the United States."  

You would not have a US tax reporting requirement.
