I saw this map in a youtube video that was mainly about the life of a German inventor who relocated to Canada in 1912. That seems to hint that this is how a map of Canada looked at that time. It is unsurprising to me to see that the provinces of Quebec, Ontario, Manitoba, Saskatchewan, and Alberta were not as extensive as they are now. And the terms "North East Territory" and "North West Territory" seem self-explanatory, unless I'm missing something (and my missing something is distinctly possible).
What was the nature of the geographic areas labeled "Assiniboia", "Athabasca", and "Keewatin"?
The fact that part of the United States is labeled "Dakota" rather than distinguishing between states of North Dakota and South Dakota suggests that this may have been before 1889 when the Territory of Dakota became two states, and thus before Saskatchewan and Alberta became provinces in 1905. Would that be correct? Did Alberta and Saskatchewan have the status of territories then?
