The court lookup tool is only as good as its data.
Thanks to David Hart for giving me the heads up that we were missing:
River Oaks Community Centre, 2400 Sixth Line, Oakville, ON L6H 3N8 with 2 courts
Queen's Athletics & Recreation Centre (ARC), 284 Earl St, Kingston, ON K7L 3N6 with 2 courts.
They are now added. If anyone sees other changes required, reply in this thread so I can make the changes.
I'm glad to help get the word out.
Technically, the Cambridge Y has 4 courts.
If you guys can keep pitching 'em in, I'll keep hitting them.
