Judging by the talk page, people keep adding joking or simply incorrect "Canadian" pronunciations to [[about]]. If you're Canadian, could you check out the audio pronunciations which are still in the entry and the IPA transcriptions which were just removed, and help us work out which, if any, are actual Canadian pronunciations of the word?
Both of the audios are right, although File:En-ca-about.ogg was once vandalized and then corrected. The IPA was right, AFAICT. w:Canadian raising says it's [ʌu] or [ɛʉ], but the entry had [ʌʊ] and [ɛʊ], which are probably either the same or acceptable variations.
