Hi folks,

Given that ids are named for the largest municipality observing given rules, and 
those named municipalities are not documented as nor likely to have diverged 
from provincial rules, then applying those ids to rural areas, especially 
reserves, would be erroneous.

In the case of Canadian rural reserves, large areas are normally covered by the 
federal treaties under which those settlements were negotiated, and if reserves 
in those treaty areas could be documented to have ignored DST, then perhaps 
better ids would be e.g. Treaty3 for the ON Lake of the Woods Area, and Treaty60 
for the ON Nipigon Lake area, given that other applicable labels are likely to 
be either confusing, excessively long, or require uncommon fonts to render?
