It is the responsibility of the home owner to make sure that if any water valve caps are protruding the driveway to contact the City of Ottawa at (613) 580-2400. You will need to request that they send a service technician by to lower the pipe and cap to the level of the asphalt. If the cap is not flush with the level of the driveway it may very likely get picked off and blown onto the lawn! So, please make sure that the city takes care of this in advance of the first snow. Otherwise, once snow arrives and covers the surface, this issue is not apparent and the city may charge you for repairs in the Spring.
