Just to sort the story out, you sent a package from a location in Canada (where I believe you live) to the West Coast of the U.S., correct?
Since it appears you've left some details out, I'm assuming there's stuff before the 2007/02/12 In Transit remark where it says it was picked up and began it's journey.
Regardless, I suppose, it appears that whomever was the recipient of the package refused delivery, and as such it's going to find its way back to you sometime soon.
Did you prearrange this delivery? Was it to the correct address? Any number of reasons could contribute to someone refusing delivery.
