I ended up ordering a HCS-40P from Clipper Creek (US), and I was pleasantly surprised when UPS delivered it from the US to Canada with no surprises (although I had it shipped Worldwide Expedited).
The totals from Clipper Creek was $589 USD, $118 USD UPS shipping (worldwide expedited), and paying $102 CDN (GST/PST tax) when UPS came to my door, the total was only $1059 CDN.
The identical (Rebranded) charger at Costco (although out of stock) would have been just under $40 CDN more ($1096 CDN) with taxes, shipping included.
Sun Country's price in Canada for the same rebranded charger was almost $180 more (rip off).
I was impressed with Clipper Creek when I called and did the order, and the shipping was only 4 days .
Thank you Clipper Creek!
(I'm still annoyed with Sun Country in Canada for not putting any efforts into being competitive).
