Context: The 2012 Oscar winning movie “Argo”. Decades ago, when the Iranian revolution was reaching a boiling point and the American embassy in Tehran was invaded, six Americans escaped and found shelter at the Canadian ambassy. To get out of Iran more or less safely they received new identities as Canadian teachers. At this point, they were told they would be asked where they came from, at the airport, and were warned that Torontonians don’t pronounce the name of their city the same way most English speaking people do.
I've searched several dictionaries and have only found the usual pronunciation.
