The RCM's book Striking Impressions says that 5,000 Expo '70 medals were minted in Ottawa. It doesn't say which medals, but I suspect that they were the Ontario pavilion medals, whose fabric is unlike most Expo 70 medals. I have also seen special coin sets of the 1970 British Columbia dollar designed for sale in Japan. So it sounds like there was at least a sales counter for the RCM there. I have a copy of the Expo 70 official guide that my father bought when we visited there. It's good for general information but gives very little data on collectibles.
