This is example is actually very different to urban planning: the Kings was urban re-generation from industrialisation, not in need of urban planning (there were already roads and infrastructure and proximity to the business district and Union Station). 

Toronto - and Canada in fact - needs proper urban planning and planning for population increases. Getting the 'bones' right of urban planning is key. For example, creating new cities on a hub and spoke design for roads and public transport. Hardwiring in cycle and walking paths and parks/green spaces. Using smart tech from the start. 

Get the bones right and the development will flourish. There is nothing more attractive to investors and developers and new businesses than to know there is already excellent public transport for workers and that they will enjoy moving to the area with their families; that the tech infrastructure is 21st century.
