Annoyingly, Siri does not have maps support in Canada, so I can't test your example, but the answer in general is 'yes'. If you say, "Set a reminder", Siri will ask what you want it to be, and then will ask you what time it ought to be at. If she mishears your time, you can say, "No, at 9:00 AM", and she'll change the time.

It is impressive technology, but right now, my #1 thing I want Siri to do is understand me all of the time. I find the speech recognition is not as good as I had hoped, and I am frequently repeating myself and trying to enunciate more.

Probably because the Canadian accent is not currently supported - US, UK, Australia, if I remember correctly.

Except there is scarcely a difference between the accent of someone living in Michigan or Ohio or New York and someone living in Ontario - the accents are certainly much closer together than US vs. UK, for example. I just think the speech recognition needs more work.

There's currently no maps or business search anywhere other than the US.
