This review is based on the atmosphere, location, & a chocolate croissant.
More a café than bakery, all the items are tucked away, behind glass - even the croissants. No macaroons were in sight during my visit. Ma Maison is located in a small strip plaza, with limited parking, on a weird, non-residential strip of Dundas. Most of their traffic is probably from people driving.
Since I was testing out croissants today - Patisserie Saint Honoré missed out since it's closed for renos?? - I opted for a chocolate croissant. It was quite average with 1 small tiny dollop of chocolate in the middle. Pastry could've used another fold as there weren't that many layers to it. Have definitely had better elsewhere!
Due to location, café itself doesn't wanna make you sit there and enjoy your caffeinated beverage/pastry. This place may do better elsewhere, but the view from the window is yet another strip mall with mainstream stores.
