What are the others? Canada, I'm sure, who else?

Canada, Marshall Islands, Micronesia and Palau. A very weird assortment of countries, aside from Canada.

It's less weird if you know that the three Pacific island countries were formerly part of the Trust Territory of the Pacific Islands which was administered by the US for decades following the Second World War and today have Compacts of Free Association with the US.

Bermuda, Palau, Micronesia, the Marshall Islands, and subject to some rules, the Bahamas and a few British Overseas Territories in the Caribbean.
