What I have noticed is that there is much to learn from many out there, and not everyone out there is 100% on the best ideas. Most tend to be something of a specialist, whether they realize it or not.
Dave Canterbury's primary strengths lay in hunting (firearms and archery) and trapping. If you want to learn the best ways to cleverly carve wood, read Mors Kochanski. If you want to see how to trap critters for food, Canterbury's videos is a good place to start.
Canterbury is one of the reasons why so many bushcrafters in the USA count a muzzleloader or a break action shotgun as part of their standard kit, especially the H&R Topper single barrel break action, which Canterbury is a huge proponent of. Canterbury is also very big into archery for hunting.
It's common with a lot of bushcraft and primitive skills teachers to have a historical anchor point, such as paleolithic, etc. Canterbury's historical anchor point is the long hunter period of the American frontier. This is when his home state of Ohio, where his school is located, was the 'frontier' and it was common for frontiersmen to travel long distances through the thick forests on foot.
The long hunter era preceded the mountain man era of the Rocky Mountain fur trade and their frontier was what is now the central part of the eastern USA, between the Appalachian Mountains and the Mississippi River. This was the era of Daniel Boone, when the wild frontier was places like Kentucky.
This is why a core part of his instructional videos is of the "21st Century Long Hunter". This is basically his concept of the long hunter with some of the equipment updated, like a break action shotgun (the H&R Topper is an 1890's design).
In North America, a focus on the mountain man era in the 1950's and 1960's produced a movement called 'buckskinning', which still goes on today. Buckskinning really came into it's own in the 1970's and that interest, plus the back to the land movement, branched out into primitive skills. Primitive skills instructors, like Olsen and Brown, and the books they wrote, became very popular.
In many ways, buckskinning plus traditional archery started by Saxton Pope (who learned from Ishi) really helped bushcrafting be what it is today, along with the efforts of people like Tom Brown, Larry Dean Olsen, Mors Kochanski, Calvin Rutstrum, Bradford Angier, John and Geri McPherson (a very paleolithic couple), and many others. Back in the day we had to use books and get-togethers, like a buckskinner rendevous and gun shows, to pass around knowledge.
Lars Grebnev (Danish but living in rural Russia, married to a Russian woman), who does Survival Russia, ironically, has a similar military background to Canterbury, combat engineer (Danish Army).
If you want to see how to deal with cold, look at how the Russians do it. Russia redefines cold into new realms of misery and danger. During WWII, German casualties would come home missing things left exposed to the cold and frozen off, like eyelids, noses, and other extremities that froze quickly when exposed, even for a very short period of time. They had to set low fires burning under their vehicle engines to keep the crank cases from freezing solid at night. Napoleon's retreating men could carve a sliver of meat right off of a living horse and the horse wouldn't even feel it.
Grebnev learned the basics of what he teaches from the locals and then developed it further by doing it.
Siberia is almost the same, exact climate and biosphere as the Yukon, only there is about 5 million square miles of it. Hunting, trapping, and fishing are important bushcraft skills there also. You see a lot of that coming through on Survival Russia's videos.
