The "conservation group" cited seems to be a rather loose congregation of people and I therefore have some reservations as to their expertise and experience in any bear recovery and rehabilitation programs.Looks like there might be a fight over the orphaned grizzly cubs the zoo took in this spring. 70 scientists and conservationists from all over the world have petitioned for Alberta Fish and Wildlife to see the cubs rehabilitated and released rather than be sent to another zoo.

I would also like to underline that the scientific evidence from the Alberta Grizzly Bear Recovery Project has shown over 30% of relocated bears die following relocation, either by the move to unfamiliar habitat, competition with resident and territorial bears and continued human-wildlife conflicts. It does not support any large scale rehab - and it is a given there is only 1 facility able to do this (and over a large span of years only 27 bears have been rehabilitated - what that means in terms of post release monitoring and survival is not reported upon).
