Stonewall/Fortress Big Oil. Remember that wall a few days ago alongside the Rotary Algonquin Fitness Trail? It, as well as this wall, are all that remain of the of the former Shell and Imperial Oil depots. These areas were abandoned a couple of decades ago, after at least one major spill that caused environmental damage. At this point Imperial Oil finds it cheaper to continue paying taxes on the property rather than cleaning up the site and putting it to better use. It’s perhaps a logical business decision but one that comes at the expense of the people of Parry Sound. (January 2014)
