Not clear in lines such as those below that Eastern, Central refer to time zone
and not the geographical part of the region - either add the word Time or some
other indication e.g. EST/EDT, CST/CDT to keep it short:

-CA	+4339-07923	America/Toronto	Eastern - ON & QC (most locations)
-CA	+4901-08816	America/Nipigon	Eastern - ON & QC (no DST 1967-73)
+CA	+4339-07923	America/Toronto	Eastern - ON, QC (most locations)
+CA	+4901-08816	America/Nipigon	Eastern - ON, QC (no DST 1967-73)
  CA	+4823-08915	America/Thunder_Bay	Eastern - ON (Thunder Bay)
  CA	+6344-06828	America/Iqaluit	Eastern - NU (most east locations)
  CA	+6608-06544	America/Pangnirtung	Eastern - NU (Pangnirtung)

Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada
