Under Alberta law, how must a taxi or rideshare driver accommodate a passenger with a certified service animal?

1. Charge an extra sanitation fee for carrying the animal in the cabin
2. Refuse the fare if the driver does not like animals
3. Permit the passenger to board with the service animal at no extra charge, ensuring the animal sits at the passenger's feet
4. Require that the service animal be placed in a crate in the trunk of the vehicle
