The pronunciation of 'bagel' varies between communities. In Canada, for instance, Torontonians and people from Montreal, pronounce it like bay, the correct Yiddish pronunciation, whereas people from the smaller towns of Northern Ontario and the East coast of Canada tend to pronounce the first syllable as bag, like in shopping bag.
