TD Bank is under a Justice Department investigation for its role in laundering money from U.S. fentanyl sales, involving Chinese crime groups and drug traffickers. This probe, part of broader scrutiny into TD's anti-money laundering practices, has revealed instances of employee bribery and has already impacted TD's expansion plans, including a failed acquisition. TD has set aside $450 million for one inquiry and faces additional penalties, alongside a recent fine by a Canadian regulator for failing to report suspicious activities.
