Yeah I was figuring about $600.00 Canadian given the low Canadian dollar. Then you have to add Canadian duties, transportation costs are also a huge factor as the product might not have shipped directly into the Port of Vancouver. On niche products like portable electronics it might first arrive in Seattle or Long Beach and then have to be trucked up to the Port of Vancouver for distribution. A huge company like Sony probably imports enough product to Canada to make it worthwhile to ship directly into the Port of Vancouver. I actual bought my A17 at a lower price ($279.00 CAN) than it was selling for in the US ($299.00) in 2014. Mind you that was when the Canadian dollar was at par with the US and my A17 shipped directly into the Port of Vancouver.
I worked in St Louis for 11 years and part of my job was handling import shipments from China and other countries to both US and Canadian retailers. You would be amazed how much shipping costs add to the price of products coming to Canada. The landed cost on products we were able to ship directly into the Port of Vancouver were significantly lower vs having to ship to the Port of Seattle first. When you ship into the US first duty has to be paid twice, once on landing in the US and then again importing it into Canada.
If you pre-order the X5-III from bhphotovideo at $399.99 US the final cost to import to Canada including Customs Clearance is about $598.00 CAN. If you wait to buy it from Gibby's it is $599.99 then you still have to add tax, in my case HST so even if shipping is free it comes to almost $680.00 CAN.
I wouldn't panic just yet on the Gibby's price, after all the bigger retailers like amazon.ca and Canada Computers aren't listing it yet. Once all the retailers have it the pricing will settle into a pretty narrow range. Then you can panic about how much it will cost.
Worst case you import it from bhphotovideo if the price in Canada is to high.
