If I told you that when I want some alone time, I go to a water filtration plant and plomp down on a patch of grass, what would you think? Stop looking at me that way! Where are you going?!? 
 
Okay, context. The R.C. Harris Water Filtration Plant is, to my eyes, one of the most beautiful spots in Toronto. On a nice day, there's no better place to sit on the green, grassy slope tucked behind one of my favourite examples of Art Deco giving life to what might otherwise be a building as appropriately boring as the idea of a water filtration plant. There's a reason it's been immortalized by Micheal Ondaatje - one of Canada's most celebrated authors - in his book In the Skin of a Lion. For the philistines among us (me), it also made an appearance in Robocop! All with good reason. That slope tucked behind the awe-inspiring building? It looks over Lake Ontario, which, if you're not paying attention, can easily be mistaken for an ocean.
It has gotten busier over the years, so here's a tip. If you want to experience it in all its glory, go when the weather is a little bit cooler, say in the fall. You'll get all the impact and feeling of the place, and also get to enjoy a bit of peace and quiet. 
 
Pro-tip: this is the perfect date destination for a romantic walk/picnic. Let the cool wind blow your hair back while you realize you might've over-salted those cucumber sandwiches.
