I'm not sure if it's really worth considering an article from the Toronto Sun, citing "people on social media". Especially when it quotes stuff like:
“Welcome to Canada, home to everyone but Canadians.”
A large portion of people receiving those benefits are literally new citizens, and while "newcomers" might not be "Canadians" by everyone's definition, they are at very least "prospective Canadians". Also, as the article points out at the end, Parks Canada has been providing free access to more and more Canadians including Veterans, youth, and those with disabilities.
