Confused about server availability

I wanted to order the RISE-S because it looked great. However as I'm in the US I'm forced to use the US version of ovhcloud website. I don't want a server that's based in europe, but willing to accept a server based in canada. I saw on OVH world website it says RISE-S is in stock in canada, but on ovh US it says out of stock? Why does that happen? I tried to check out on OVH world but I can't make an account there as they don't allow mainland US customers to do so.

Would support help me out here if I asked or is there some weird reason as to why this location is in stock for world but not for US website?
