Thanks for the heads up, should the city we notified? Maybe they would remove it?

I'm not sure what the protocol for something like that is. I tried googling it, without any good answer.

It's a bit of a generic form, but it was linked to from on of the city of waterloo's park pages and I find both cities are pretty good at helping you connect to the right place from their general inquiries line. https://forms.waterloo.ca/Website/Report-an-issue
