Canadian jurist Kimberly Prost has become a central figure in a deepening rift between the Trump administration and international legal institutions. A veteran of the Canadian Department of Justice and a current judge at the International Criminal Court (ICC), Prost found herself on the U.S. Treasury’s sanctions list in August 2025.

The U.S. State Department, led by Secretary of State Marco Rubio, designated Judge Prost for her role in authorizing an investigation into alleged war crimes committed by U.S. personnel in Afghanistan. The administration has characterized the ICC’s actions as “illegitimate judicial overreach” and a threat to American sovereignty.
The Personal and Professional Fallout
- Financial Paralysis: Her U.S.-based assets are frozen, and most international banks (including Canadian ones with U.S. ties) are wary of providing services to sanctioned individuals.
- Travel Restrictions: Navigating international travel becomes a logistical minefield, as airlines and foreign jurisdictions fear “contagion” from U.S. secondary sanctions.
- A “Chilling Effect”: Human rights advocates argue these measures are designed to intimidate the judiciary and normalize the use of economic warfare against legal professionals.
Canada’s Quiet Diplomacy
While Canada’s Ambassador to the UN, Bob Rae, initially called the move “disgraceful,” the official response from Ottawa has been notably reserved. Despite Foreign Minister Anita Anand raising the issue with U.S. officials, the Canadian government has yet to issue a formal public condemnation or invoke the Foreign Extraterritorial Measures Act (FEMA) to protect Prost from the impact of these sanctions on home soil.
“If we don’t do anything about this now… we will normalize the use of coercive sanctions against people who have dedicated their lives to serve others.” — Mark Kersten, International Justice Expert.
