Good point.  We are on the few countries that still does hand counts, I think the UK is the other (although unlike us all the ballot boxes are driven to a central location and counted there, their country is dense enough ridings are never that big) so pretty hard for the Russians or any other foreign power to tamper with it.  Heck if the Tories choose Leitch and Trump's relation sours with Trudeau, maybe Trump will order the US to try to hack if he is able.
