if a couger is intent on eating you you will : a) not know its there, b) not have time to take saftey off, c) not relize it has attacked untill your bleeding out and paralized.
yes there have been "cat" sightings in eastern ontario, the chances of you being thought as prey by one of these is slim to none as they have plenty of easier prey available to them in the wild the commen occerences of cougers attacking humans are usualy due to logging pushing them out of the mountains,lack of natural prey due t obad winter/supply, over devolopment in there natural habitat, or any combination of the previous. these sorts of incidences usualy happen out west in the rockies. and ontario doesnt have near as high a population per acre of wild habitat as they due out west and there food supply is rather large without the need to be bothered with humans. in time *15-20 years* the needed circumstances may arrise to force cougers to openly attack humans as they do outwest but for now you should be safe.
PS mike i guess now is a good time to tell you that there have been 8 witnessed couger sightings where we are going bear hunting eh LOL
