That's very interesting, they really really should be looking at growing this as an office node, it is just not dense enough and no new growth has happened in decades, and it has a very high availability rate I think the high teens. Some good new though recently, the huge block left by direct energy, American Express moved their HQ from Markham into part of that space. Hopefully if they improve the public realm ... maybe a downtown Markham type project ?? I think that would help a ton.
Some of me wishes the Shopes at Don Mills == Downtown Markham, with way more office space planned, I think this is an even better location for such a development though !
