It seemed unlikely to me that the statement about the Yukon in line 1844 below "This is still valid;" was still valid, except in the sense that Yukon standard time may still be defined as GMT-9, although standard time in Yukon has not had that offset, and the name has not been used with that meaning, except in some historical sense, since 1973.
So I tried to trace the history of Yukon time and found the following regulations, giving the reference title and URL if found, regulation name, and relevant quote if available.
Each regulation specifically revokes its predecessor.
The final reference is to the current Interpretation Act authorizing and resulting from these regulatory changes.
Only recent regulations were retrievable via Yukon government site search or index, and only some via Canadian legal sources. Other sources used include articles titled "Standard Time and Time Zones in Canada" from JRASC via ADS Abstracts, cited by ADO for 1932 in northamerica:1456, and updated versions from 1958 and 1970 quoted below; each article includes current extracts from provincial and territorial ST and DST regulations at the end, summaries and details of standard times and daylight saving time at many locations across Canada, with time zone maps, tables and calculations for Canadian Sunrise, Sunset, and LMST; they also cover many countries and global locations, with a chart and table showing current Universal Time offsets, and may be useful as another source of information for 1970 and earlier.
The coordinator should decide how much Yukon time history should change, relative to that currently documented at:
