Where In Ottawa LVII

I know: it's a long weekend, and a gorgeous one at that. You're either relaxing at home or putting your feet up at the cottage: either way, you're soaking in the wonderful late-summer weather, and reading a blog post is far from your mind.

Or is it?

Why not do something frivolous like try to solve a photo challenge?

Because it's a holiday, I thought I'd go easy with the latest Where In Ottawa challenge. If you've never played this contest, here are the rules:

Below, you will see a photo that I shot somewhere in Ottawa. Your job is to simply identify the location and leave your guess in the Comments section of this blog post.
Please, only leave a guess on this post. Do not contact me through Twitter or through Facebook, or even by e-mail. I need everybody who plays to be able to see the guesses, and the only guarantee that he or she will, the only guarantee that this contest is on a level playing field, is for me to accept guesses that are left on this blog post.

If you try to guess by any other means, whether you're right or wrong, I won't respond to that guess and you can't win.
For every day that the challenge isn't solved, I'll leave a clue in the top-right corner of my blog. Above my photo.
The first person to correctly identify the location wins the challenge. You can guess as many times as you like. Only bragging rights are claimed by the winner: there is no actual prize.
Ready for this month's photo? Here it is:
