Here is what is says about Aboriginal hunting rights in BC...
ABORIGINAL HUNTING
The first priority of the Ministry of Environment is to ensure the long-term conservation of wildlife populations and their habitats. The Ministry also recognizes that Indian people have aboriginal rights to harvest wildlife for sustenance (food, social and ceremonial purposes) in their traditional areas.
Such uses of wildlife must be sustainable, and harvesting methods must not
jeopardize safety or the use and enjoyment of property. Any hunting of wildlife species for sale or barter, in whole or in part, is not legal, except as authorized by regulation or where there is a demonstrated aboriginal or treaty right to do so.
There is more but irrelivant to this discussion here is what it says about Metis hunters...
Métis Hunters
A reminder that all Métis individuals intending to hunt in the upcoming season are required, under the Wildlife Act, to hold a valid hunting licence and comply with all appropriate hunting regulations.This includes obtaining appropriate species licences and complying with Limited Entry Hunting Regulations.
Now with this all said even in BC if the grizzly was considered endangered it would be illegal to shoot the grizzly if you are a native unless it was in a defense situation.
Not sure why what you quoted would prohibit killing a grizz Camp. Lots of traditional use of grizz by First Nations people in B.C.....read social/cerimonial.
