Hi i am looking forward to explore winnipeg this coming october. what are some good places or events to see? im planning to stay 3 days..
Have you taken a look at the Winnipeg Tourism site? That would be a good place to start.
You can check their events calendar for special festivals, etc that would be on during your stay.
Good advice from phpr, that is a good website. Also look at the "things to do" listing from Trip Advisor
Your profile does not say where you are coming from, so just to let you know, October can be gorgeous or freezing, so check the weather and pack accordingly! :)
