Do you know What's the hour for the openhouse? I can't find it in their website. Thanks for your info. about CMS Thornhill campus. I went to their open house on Thursday and feel is not as good as TMS( no space in Sept.) and Richmondhill Montessori School( location not as good as CMS). I found there's not much posters and learning decorations . As I know, the Montessori method is to provide a learning environment so that the kids can explore and learn by themselves. These blank walls don't like learning friendly. I have another concern about the language. It looks like the majority of the teachers and the kids don't speak english as their fist language.Is there any problem for the kids to speak good Engish ?
