Camp inmates coined country-names like Canada and Mexico for depot sections of Auschwitz

Evidence

Canada (“A name given by Polish prisoners to the section in the camp where the belongings of deported Jews were sorted and stored. There almost anything could be organized. Obviously the Poles imagined Canada to be a country of unlimited wealth”) and “Mexico” (“The name Mexico originated in the spring of 1944 when prisoners were quartered in this not quite completed camp without any clothing whatsoever. They wrapped themselves in coloured blankets which made them look rather like Mexican Indians”) are terms that may not precisely “belong” to LTI to the extent that they appear to have been used only by the camp inmates, rather than by the SS or German soldiers (I am quoting from the glossary provided at the end of Filip MUller’s Eyewitness Auschwitz: Three Years in the Gas Chambers. — Gil Anidjar, The Jew, the Arab, 1191

Categorization

• CANDY: The image of prisoners nicknaming a sorting depot ‘Canada’ because Poland imagined it a land of unlimited wealth is a striking, quotable tidbit.
• QUESTION: Why Canada specifically as the imaginary land of plenty for Polish prisoners — what postwar Polish image of Canadian wealth produced this? Worth chasing.
