Even when I was telling Amazon.ca the specific stuff I wanted it was still like "Here's a wireless mouse!" or "Here's a mouse with only 2 buttons or a mouse with 20 buttons!"
The ones you listed don't seem to like anything other than a USA ZIP code (even when I try to tell it I'm from Canada), so I'm guessing they aren't available for shipping to Canada?
EDIT: It needs to be wireless because apparently something to do with my remote desktop connection into work absolutely fails when something is connected wirelessly. I had massive issues for the first few weeks when I started working my current job, where one click would often be counted as two. After a couple of weeks dealing back and forth with IT, one of them asked if I had any wireless devices connecting to my home PC. I swapped my wireless mouse with a wired one and it worked perfectly. But now my only good corded mouse puked, and I'm left with: a 20-year-old Microsoft-brand mouse with only 3 buttons, a mouse that has almost no short-ranged sensitivity, and a mouse that glows directly into my retina unless I hold it at a weird angle.
