Alaska Boundary Dispute and Ontario-Manitoba Boundary Map
Two of the sharpest boundary arguments in Canadian history share a single plate. The Alaska boundary dispute map lays out the rival claims of Great Britain and the United States along the British Columbia and Yukon panhandle, alongside the awarded line that finally closed the question. Beside it sits the Ontario-Manitoba boundary map, showing the Dominion and Manitoba case for pushing Ontario’s western limit along a due north prolongation from the junction of the Ohio and Mississippi, and the competing height of land between the St. Lawrence watershed and Hudson Bay.
The plate comes from the 1st Edition of the Atlas of Canada, published in 1906 by Natural Resources Canada, and records the historical claims as they stood at that date. Major railway systems of the era are drawn in as well, offering useful context for how rail shaped territorial argument.
