Your item was delivered by UPS to the hub.
They will add it to a container of other shipments coming to Canada and reship it.
Once in Canada the container will be opened and resorted.
Yet another shipper may be subcontracted to do the last mile delivery to your home.
And the tracking number may change.
Take a deep breath.
Mark the last day for delivery (August 14) on your calendar.
It will arrive by then if not sooner.
Never watch tracking.
