on amazon you're looking at the international version H870, it's GSM only and won't work on CDMA like verizon, also idk if it has wireless charging or not (source: https://www.techwalls.com/lg-g6-model-numbers-differences/)

The version at B&H is US997, it works on GSM and CDMA, technically the u.s. cellular version, but looks like that's going to be the u.s. unlocked version. The u.s. unlocked version on Amazon is here: https://www.amazon.com/dp/B06XYRS7CT

Or you can pre-order direct from LG here: http://www.lg.com/us/cell-phones/lg-US997-Black-Unlocked

edit: for the sake of completeness

Here's the link to B&H: https://www.bhphotovideo.com/c/product/1322814-REG/lg_g6_us997_32gb_smartphone.html

And, here's the link to B&H where you get an LG Watch Style for an extra $50 (instead of $250): https://www.bhphotovideo.com/c/product/1335245-REG/lg_black_g6_32gb_smartphone.html

I'm from Canada too. I'd order the LG G6 from Amazon.com. They are currently on sale and being the US variant, you can unlock the bootloader and root it. Comes to about $620 after conversion fees. https://www.amazon.com/gp/aw/d/B06XYRS7CT/ref=mp_s_a_1_5?ie=UTF8&qid=1504654577&sr=8-5&pi=AC_SX236_SY340_FMwebp_QL65&keywords=Lg+g6&dpPl=1&dpID=41fi5gB%2BWsL&ref=plSrch
