I would certainly agree that not only indigenous but also non-indigenous individuals who may confront dangerous, predatory animals in the wilderness may have a need for rapid follow-up shots. In fact, there are quite a number of other situations where rapid follow-up shots are required. For example, in the control of feral pigs, which is an increasing problem in agricultural areas of Alberta, there definitely is a need for that capacity.
I would also point out that one example of many of the firearms that would have been affected is the SKS rifle, which has been used for hunting in a great many situations, particularly by hunters on a budget. The reason why that particular firearm has been very popular is that it was very cheap. At one point, you could get one for $89. The ability to have a hunting rifle capable of taking deer reasonably and to have multiple follow-up shots if they're necessary for the control of a dangerous animal, for that low a price, led to its very widespread sale across Canada.
