Don't confuse order (special order) with "on reserve". It is special order (i.e. a bundle not listed on Lexus.ca), you can probably get it. But will have to wait 3-4 months. If it's a config on the Lexus.ca site then you can reserve that config, and you're likely only looking at a couple weeks.
I also have a 6mt with sport package arriving within the next 2 weeks. The dealer order form showed availability for the sport package as a "D" option. hopefully it's just a problem at the lexus.ca website.
