I'm gonna keep plugging it as an option for the price conscious Canadian... check out Costco, and look for the Haier 65" 4k TV. Some people have complained about things like vertical banding, but Costco has a very liberal return and exchange policy. The TV is $750 before tax - buying from Costco automatically gets you a 2 year warranty - extending to 5 years was something like $50.
It won't get you HDR - but nobody will at that price at a TV anywhere near that size. If HDR is a must, this option isn't for you. If 120 Hz is a must, this option isn't for you.
I have been thrilled with mine, especially at the price. I was looking for a cheap TV to match with a radio-computer project of mine (I gutted a 1930's standup radio, and am retrofitting it with its own sound system and computer) and was planning on a 46 to 50 inch 1080p TV, but when this came along, I made the jump.
TLDR - the Haier 65" 4K TV at Costco is a dirt cheap way to get a large, 4K TV in Canada. It's not for everyone, but if it matches what you're after, it's a great deal.
