How much I have understood this is about mining datacenters in Canada,not US-and the climate in Canada is much more favorable then is USA for mining.Of course the price of electricity and labor costs are far less in China,but this is no more option for anyone doing anything regarding cryptocurrency.
This doesn't like a feasible fit because electricity is cheap in china, the biggest 2/3rd of BTC is mined. Other place where is BTC is mined extensively is European countries where temperature is low. That provides for free cooling of mining labs. Northern US provides neither of those in the first place. Secondly, roughly 6 million are left to be mined anyway. So, better invest in mining of some other alts instead of BTC.
I am not sure about Northern USA climate,but Canada have fairly low temperatures throughout the year :

BTC to be mined,more precisely 4,178,738 currently,there is still plenty of room for profit-otherwise everyone would listened your advice and leave
BTC mining.
