If the Ontario government would modify the 'Places to grow act' so we could actually use land outside the GTA this problem would be resolved fairly quickly.  They assumed by opening the floor gates to immigration, then land locking the surrounding land outside the GTA, that it would create their vision of a mega city full of condo's and unicorns and everything would be perfect.  Typical government boondoggle.  This all about urban intensification, side effect is high prices.
