Toronto Earth Hour Themes ?
I've been looking too but haven't found a lot. Here's what I know...
Rosewater Supper Club. http://www.libertygroup.com/evites/rwearthhour/index.html
Royal York. http://tinyurl.com/cazgxm
Novotel (on Esplanade). http://www.thestar.com/article/608257
Last year I was at Mitzi's Sister and they had lights out & special drinks. But I don't know if they're doing it again this year.
FYI, here's last year's thread about Earth Hour dining. http://chowhound.chow.com/topics/503863
