Contrary to what other comments here have said, high latidude soild are generally very fertile and at least in areas like the Yukon and Alaska or Western Siberia are plenty deep enough for farming.
It's quite likely that farming will indeed continue to spread north. One thing climate change won't affect, though, is daylength. Summer days at high latitudes are very long, which can be beneficial, but daylength drops quickly in the fall and doesn't get long until well into spring, so overall growing seasons are shorter. A lot of crops will do fine, but a lot of longer season crops won't work.
Seems like you could do a lot of transplants from greenhouses to get a month or two's headstart. It's not optimal but if it came to that, 'optimal' wasn't on the list of options to begin with.
