Pandering to our Inner Joe

' Ontarians to have say in whether province changes daylight saving time'. This stikes me as meaningless pandering to Canadian ego, our Inner Joe -- 'I don't change my watch when Americans do! I am Canadian.'
The Ontario attorney general Michael Bryant is quoted in this story as saying "Our government's going to do what's in Ontarians' interests, which does not necessarily mean automatically following in lockstep with the United States government's change to daylight saving time."
So I guess it is in Ontario's interest to dither, causing disruption and anxiety to businesses across the province before making the obvious decision, eh?
Can anyone give me any reason for Ontario, or any other Canadian province which is already on DST, to not just follow the American hours for Daylight Savings Time? Most provinces have significant US border trade plus Ontario has industrial involvement in US industries like the auto industry, so why on earth would Ontario NOT want to be on the same time as Detroit and Buffalo and New York?
Being in Saskatchewan myself, where we don't bother to switch times anymore, we feel that time is just an arbitrary constructed concept anyway.
We don't change our clocks because of the very early evening or very late morning which DST would cause to half of the province. Being on Manitoba time in the winter means Yorkton isn't dark by the time school lets out, while being on Alberta time in the summer means Lloydminster gets longer summer evenings. It works out for everything except the TV schedules.
