I always thought it was 60hz for ever!, but (googling) 25 -> 60 in 1949+/-, (in canada) you're no spring chicken!! :)
A few years ago, I read a book about power systems in Ontario. There were a few different frequencies, other than 25 & 60 Hz. There were even rotary converters (combination motor & alternator in one unit) to change the frequency. I seem to recall there was still one to convert to 25 Hz for industrial users in the Buffalo area.
