I've seen references in the past that would indicate that there are businesses on the US side of the border that advertise their weapons storage services, but try as I might I can't seem to Google any of the businesses to my desktop.

Another option that comes up quite often is to leave it with a gunshop on the US side for a detailed cleaning with a pickup date that coincides with your return. The cleaning fee is probably equal to any storage fee and the transaction will not have to been shown as a "transfer" on the books.
