Apparently little known fact - the Alberta Children's Hospital does see adults, when a specialist for their condition is on staff there. That's how I first came to walk through their doors 8 years ago, & was at one point visiting three times a week. I have had numerous tests there including a brain MRI, strength tests, & enough vials of blood drawn to fuel a vampire for a few years. I receive a brown grocery bag full of meds from their pharmacy every 3 months. And I have eaten quite a few dishes in the cafeteria* while waiting for my ride.
So, I can confidently state that this is a top-notch medical facility. Every department I have encountered has been professional and friendly, and all seem to enjoy caring for children. The equipment is fairly up to date, & the lab techs are pros at difficult blood draws. The building is fairly new, bright & cheerful, with activities for kids tucked around most corners.
(* I would not recommend this as a destination to eat, but they do have some healthy snacks, & I have liked the soup/chili well enough when I have needed a meal)
