In the case of the American Embassy, the building goes deep underground, therefore a tunnel running along its basement could cause an issue. Even when the Confederation Line was built, the contractors pierced a hole in SunLife's parking garage.
Even if the risk was slim to none, there is still a perception that it could be unsafe. During the planning stages, some government officials raised concerns about a tunnel's risk to the Parliamentary Precinct.
