That image is the district of Alberta. Alberta joined confederation looking like it does now by combining woth the district of Athabaska.
1905 – The provinces of Alberta and Saskatchewan are created out of the districts of Athabaska, Alberta, Saskatchewan and Assiniboia; the District of Keewatin is transferred to the newly defined Northwest Territories
True, same is true for Quebec if you check the 1905 map, however what they would get upon separation would be somewhat similar to the yellow portion here, though I think some of the northern part of that yellow portion they lose as well.
It’s not the same as Québec because they joined in 1867.
The big point is that the “borders at the time of joining confederation” would give them the whole slice. Thiugh I agree it is unlikely they get the whole slice, and the entire thing would be a protracted international legal battle with border disputes for decades.

My point being, there’s a strong likelyhood they would not walk away with the whole province.
