Ottawa remains silent on U.S. sanctions against Canadian ICC Judge Kimberly Prost, as legal experts urge Canada to defend judicial independence.

The Canadian government is facing growing questions over its response to U.S. sanctions imposed on Canadian International Criminal Court Judge Kimberly Prost, as Ottawa refuses to say whether it will support her legal challenge before an American court.

Prost, who was born in Winnipeg, is among three ICC judges suing U.S. President Donald Trump and other senior American officials in federal court in New York. The judges argue that the sanctions are unlawful and were designed to punish and pressure them for carrying out their judicial duties.

Washington sanctioned Prost in August 2025 over her involvement in a court decision authorizing an investigation into alleged crimes involving American forces in Afghanistan. The measures reportedly left her unable to use credit cards or access services provided by many major online companies.

Despite Canada’s longstanding support for the International Criminal Court, the federal government has not publicly condemned the sanctions. Global Affairs Canada has also declined to clarify whether Ottawa intends to intervene in the lawsuit or file a legal submission supporting Prost.

Former Canadian diplomat Sabine Nolke said Canada could demonstrate its commitment to international law by filing an amicus brief in the case. She argued that Ottawa should speak more clearly in defence of judicial independence and the rule of law.

The three judges maintain that the sanctions violate their rights and exceed the authority granted to the U.S. president. Their legal team has also requested a preliminary injunction to suspend the restrictions while the case proceeds.

The Trump administration, however, says the president acted lawfully under U.S. emergency economic powers legislation. A White House official described the ICC’s actions involving the United States and Israel as a threat to American national security and foreign policy.

The dispute has placed Ottawa in an increasingly uncomfortable position. Canada regularly presents itself as a defender of international justice, yet its reluctance to confront Washington over sanctions targeting a Canadian judge has raised questions about how far that support extends when relations with the United States are at stake.
