1) Safety - zero loss of life is expect.
2) foreign workers - in Europe
3) consultants
4) choosing the same companies, even after they were over budget.
5) needing that ribbon cutting pictures for the next election
6) Not using off the shelf stuff. TTC gauge as an example.
7) Requiring "built in Canada" for much of it.
8) Having a long term maintenance contract done by the private sector
9) North American railway standards are higher.
10) Incremental construction is frowned upon.
How is that for a start?
While these may be "bad things" that make our costs higher, most of them may be worth the higher cost.
Let me remove the ones that are complete nonsense from the above first.

10) Incremental construction is frowned upon.
Now lets take a closer look at the above, most of which is still dubious, but merits further explanation.
We do spend excessively on business cases and E.A.s that are improperly scoped. However, the total cost in $$ against the project budgets is relatively small, the bigger issue is wasting time, and misdirected public expectations on what's up for discussion.
4) choosing the same companies, even after they were over budget.
There is something amiss in the way we bid out huge projects. I'm not a fan of giant P3s for a host of reasons, one of which is that they severely limit the number of bidding companies.
We recently saw the new Niagara hospital project end up with only one bidder. While we haven't seen that on any rapid transit projects, we do have too few bidders, because we've scoped projects to require such deep pockets and such risk tolerance that most projects are beyond the scope of most bidders.
We really should look to a mixture of doing more work in-house (see everyone's favourite low cost transit building Madrid), as well as smaller packages of private work, without the finance and operating components rolled into the build, so that we get more competitive bids.
8) Having a long term maintenance contract done by the private sector
While there are good reasons to consider bringing this work back in house, in many cases, it doesn't really inflate the cost of the construction, though it certainly results in a higher contract award number when those disparate items are all rolled into a single bid.
Its not as if in-house maintenance services are free or even cheap, its that that cost is kept separate and annual rather than lumping a 25-year forward price into an announced winning bid.
10) Incremental construction is frowned upon.
Phased opening of new transit lines have many desirable qualities, they do allow for quicker delivery of the first opening, for steady progress, for incremental gains in construction knowledge from continuous building and they make it easier to re-tender to new companies for subsequent phases of work, resulting in more manageable tender packages.
That said, they don't directly lower construction costs, they do have some incremental impact vs over-sized packages that are higher risk with fewer bidders.
