Unfortunately he's not kidding. Future Shop doesn't have it either, and the last person who visited a Walmart said they knew nothing about it. Amazon.ca only has this. Amusingly, they do list Destiny's Embers in the books section.
So, I can't think of anybody in Canada that would have it at retail. I get why that's true in Quebec (no french translation or translated packaging), but it's pretty strange for English Canada.
Your options are to cross the border and buy from the US, order from the US (Amazon.com lists it, or Stardock directly), or just buy a digital copy and grab one of those archival DVDs when they come out.
