My concern about these changes is that I seem to remember that some first nations in those areas did not use daylight-savings time on their reserves, and that they were real but very small 'zones', not the large zones they ended up being assumed to be.

Unfortunately I have no documentation either way on this.

Thank you for doing that investigative work. Proposed patch attached and
installed into the tzdb development repository on GitHub.

This patch follows your suggestions, except that it moves Nipigon's and
Rainy River's dubious data to 'backzone' instead of removing them
entirely, as I worry that some users will want the appearance of
completeness no matter how illusory.
