Often, statistics specific to a particular region (e.g. province) can be easily found on department, ministry, or city websites. For example, a Google search for Ontario energy statistics will lead you to the Ontario Energy Board. A Google search for Canada mining statistics will lead you to Mineral Statistics - Natural Resources Canada. It is important to ensure that the information is coming from a reliable source - look for statistics from governments or international organizations or societies.
