Why are people in this city so flakey and noncommittal?

So I've lived in few cities/countries both in an outside of Canada, one thing I noticed that is unique to this city that really annoys me about the people here is flakiness and the noncommittal to plans.

I feel one of the reasons find it hard to make friends here is because people just let you down constantly and people don't really respect other people's time.

Has anyone else found people in this city to be very flakey?
