Bah... I went to double check my receipt from the Ottawa Apple Store. You are probably right about the Retina as there is no mention of it in the detail. All the rest is accurate re. MacBook Air. Price was $1849CN, which was about $1780US at the exchange rate at that time. Walkout price including a case and tax was $2170CN. Upgrades above base configuration installed at the store.
Do not assume that a non-USA product line up is going to be exactly configured as a USA line up. I didn't realize this myself until I popped into the web Apple Store after your comments.
