Taxis are expensive. I want to say $50 with tip? It's been two years so I'm not sure.
Otherwise I find the airport to be fine. It's clean and comfortable and easy to navigate. I had to update my wife's NEXUS information (no NEXUS office at my home airport) and I took advantage of being there to do it, and had no issues finding it at all.
There was a good pub (D'Arcy McGee's) that I wish I'd known about before I was flying home.

I was at their main pub near Parliament Hill and really enjoyed it. I'd stop at the airport location for a drink if I ever were there, with time, in the future.
