The company I used to work for uses ACE for deliveries for product transfers from Metro Vancouver stores to other stores in the interior (Kamloops, Kelowna, Vernon, etc.) for the past 3 years. It's really dependent on the driver. But for the most part, they arrive on time (we use next day delivery though).
With the tracking number, the operator should be able to tell you whether it's been picked up from the shipper, sorting at their location, and/or whether it's en route to be delivered. They won't be able to tell exactly where the package is unless the operator calls the driver for his/her current location...
