Just a comment from down under, it's interesting to note that while US
government maps are public domain, from the Sanborn comments of late,
private companies seem to have 90 years copyright.

Here in Australia, government (any government, local or
foreign) copyright is 50 years and private companies 70 (increased from
50 in 2005 as part of Australia-US "free"-trade agreement, upon
insistence from the Disney Megacorp), so Sanborn maps held by Australian
institutions would be public domain if published before 1955, and those
from 1955 will become public domain in 2026.

Is there much difference between Canadian and US copyright durations?
