I have to disagree with you on several key issues For example the horses mouth is extremely likely to be biased in the horses favor If for example this local government had a reputation for corruption or inefficiency or waste their own website and other government bodies would be the last places to find references to that Besides primary sources cannot serve as an indication of notability On the other hand Wikipedia is independent but it does not consider itself reliable The articles content is not really supported by the sources either and I think at times its simply wrong because you took too much poetic license For example beautiful ecosystems  valued by all British Columbians  really Theres not a single person in British Columbia who doesnt value these ecosystem So the article would have to be rewritten significantly to remove editorializing personal opinions hyperbole and the like So in summary it may well be possible to write an article about the Islands Trust  but it would have to differ from this one in sources tone and likely content
