machz990, both of those e-mail addresses are correct. Try again. If it still comes back you might try calling them.
I just jumpseated from CAN to NRT from the airport hotel and the ramp set that up. I'm not sure if they will do the same from the Holiday Inn, but you might try calling one of the CAN FOA's (the numbers are on the pilot.fedex page under general info, ramp contacts). The FOA's at CAN should be very helpful.
Make sure to contact the operating captain and get permission for the ride and you might also ask him if you can ride in the van to the hotel. If there's not enough room, it's pretty easy to get from the airport to the hotel via train and subway, assuming you're not coming in too late. There's people who speak english at the help desk in the terminal that can point the way.
Also, a cab will run about $150 at the current exchange rate.
