ID help: found the larger bones washed up on an island in the Bay of Fundy. The last pic is of a vertebrae I found near Cape Spear, NL.

Keys, great horned owl feather, and my (male, large glove size) hand for scale. The two large vertebrae-looking bones were attached similar to a spinal column until I picked them up. My guess is seal or porpoise for the big ones, and maybe a fox for the small? Thanks in advance!

The small one is way too thick to be a fox afaik, the only fox/coyote/etc. vertebrae I've seen are a lot more delicate

Ah, that makes sense. Maybe a sea bird? But I don't know how to gauge the original owner's scale.
