Ottawa International Airport YOW to and from Ottawa city｜Airport shuttle

There was no sign at the pick-up area, specifically stating that we needed help moving our luggage at the disembarkation area, but in fact we took all the luggage ourselves and walked outside the airport to call the driver to inform the driver. What is the difference with Uber, but the price is much more expensive. It is recommended not to use it, just call Uber at the airport.
