Toronto does have a way. Take the Island Airport Tunnel, for example. Toronto’s tiny tunnel took 3 years to complete a mere 165-metre passageway (260m overall), and the original budget was eventually quadrupled. Meanwhile, Europe’s humongous Channel Tunnel took 6 years to go 37.9 kilometres under water (50.5km overall) with a cost overrun of just 80%. The differences are … astounding.
