I meant "Asian grandmothers" in a purely stereotypical way...there's a chance most residents of Downtown Markham could be elderly/Asian, in which case a generic New Urbanist space may not reflect how people will actually live. There may be gazebos and rose gardens everywhere, but would Asian grandmothers rather have benches and ponds, or paved areas good for tai chi? Markham seems like a municipality that is realistic enough to recognize what people actually want/need and not simply get caught up in what would be the most "well planned" or "well designed," although I do expect a modicum of Disneyfied quaintness, such as superfluous gazebos or doomed-to-failure-and-will-go-down-in-flames-with-the-best-intentions cafes with patios, etc.
Perhaps the best recipe for success would be for the residential/retail components to truly be an amenity for the office parks (cheap rental condos for young tech guys, lots of places to eat out for lunch, stores to shop at on the way home, etc.), even though this could be considered urban seppuku. There must be some kind of parallel in the US, where a suburban downtown/node springs up with condos and feigned urbanity and functions as a successful community on some levels even though it's all just a glorified office park in the end.
