I am not sure if you would call it a "double entendre" or what, but it's easy to take the writer's phrase and to apply it in a different way, the part where he complains:

"Still, stand in any major intersection these days and it’s almost impossible to tell what city or country you’re in."

Hello?

Now, okay, he happens to launch that complaint by bristling mainly at the USA, at how the golden arches of McDonald's are from Paris to London to Hong Kong to Toronto (gotta include the shores of Lake Ontario in any list of great cites nowadays, apparently) , and how now we see European-originating clothing flooding in on a dime in the same cities.

But wait a second. How would the writer square his affection for Canada's multiculturalism with his own phrase I quoted above?

Stand in parts of Vancouver or Richmond, hard to tell you are not in Hong Kong, stand in parts of Toronto, hard to tell you're not in the Caribbean.

How does he justify his bristling at one and embracing the other?
