Stunning facade, decent interior, rip-off price. How can they justify nearly $20 for an entrance fee for this place? $10 would be more than fair. Really the only thing inside worth seeing is the view from the turret and the gardens. The stables don't even warrant the walk through the tunnel, and the rest of the house is lackluster, with trite recordings on the audio guides (which were, thankfully, free).
I'm glad I visited, but I'd be hesitant to recommend this as a Toronto "must-do," as others had for me.
