Pretty much.
Any Big Dig in Toronto would cost more than the big dig in Boston. Just by virtue of the cost of unionized Canadian construction workers alone (the City of Toronto will only hire unionized contractors because they are in bed with the unions).
Personally, I'd rather see them spend money on building more subways in Toronto than EVER building a tunnel to replace the Gardiner. They would tear down the Gardiner and infill the land with more and more banal looking boxes (condos). I'd rather look at the Gardiner thanks.
Big Dig was a full on Union theft operation, but still a good outcome.
