This is a very silly idea, Canada's population isn't even that large. Why would we build new cities that have no economic basis when we could just scale up our existing cities? Toronto could be a megacity but it isn't currently.

Such a thing has been done in the UK - as for "no economic basis" - Wikipedia says "Milton Keynes is among the most economically productive localities in the UK, ranking highly against a number of criteria. It has the UK's fifth-highest number of business startups per capita" This "very silly idea" been done and proven in the UK, when overcrowding made it necessary, and quite likely other countries - I bet China's done it. Why does any new city start? Historically its often been due to a natural resource that could be traded, transport links or some such, but there's no reason why this couldn't be jump started as has been done in the UK. Especially now with tech and many people WFH. Also from what I heard, Toronto was already considered a hideous sprawl, not necessarily desirable to further extend.
