Toronto (ontario,Canada) was/is called "Hog Town" also, for being the main pig slaughter place for Canada. I'm told it was once called "Muddy York", for when it didn't have paved streets (wood was lain down, and then proper roads over time...).

Scarborough, part of Metropolitan Toronto on the fringes is dubbed "Scarberia". In winter it really does have the feel of being in Siberia.

A few minutes drive from where I live now, North Hampton is called NoHo, as a play on SoHo.
