Send your question to LFCA in Toronto. Direct it to Training or Range Safety. The range was cleaned up when returned to the natives, so there will be a file on it that will be kept for a long long time. Ask what was done, who was contracted and where any artifacts were taken. Just start the conversation and do your research. But, I suspect the range was truly cleared and anything not current or live immediately sent to scrap. Get it done would have been the political imperative.
