Canadian Diplomats Press Carney on Israel Sanctions as Gaza Ceasefire Frays

Nearly 200 former senior Canadian diplomats have called on Prime Minister Mark Carney to impose robust sanctions on Israel over deteriorating conditions in Gaza and Lebanon, an unusually direct intervention by a generation of former officials that has put renewed pressure on the federal government's Middle East policy. The appeal landed as an Israeli airstrike in Gaza on Friday targeted the leader of Hamas's military wing, the latest in near-daily strikes that have continued despite a fragile ceasefire reached in October.

The deteriorating conditions on the ground, combined with mounting domestic pressure inside Canada, have created one of the most sensitive foreign-policy challenges of the Carney government's first year in office. The Prime Minister has publicly expressed concern about civilian conditions in Gaza while resisting calls to break with Israel in a way that would isolate Canada from key allies.

The diplomats' appeal

The open letter, signed by almost 200 former senior Canadian diplomats including former ambassadors, high commissioners and assistant deputy ministers, calls on the Carney government to adopt sanctions targeting Israeli officials, settlers and entities responsible for unlawful conduct in the Palestinian territories and Lebanon. The signatories argue that Canada's existing approach is inadequate to the gravity of the situation.

The letter cites the cumulative civilian toll in Gaza since October 2023, the resumption of intensive Israeli operations even after the October 2025 ceasefire, the destruction of civilian infrastructure and the difficulties humanitarian organisations face delivering aid. It also references reports of escalating settler violence in the West Bank.

Federal government officials have acknowledged receipt of the letter and indicated that Canada's Middle East policy will continue to be reviewed in light of evolving conditions. The Carney government has previously expanded sanctions targeting Israeli settlers accused of violence in the West Bank, while stopping short of broader sanctions against Israeli officials or institutions.

What is happening on the ground

An Israeli airstrike in Gaza on Friday targeted Izz al-Din al-Haddad, identified by Israeli Prime Minister Benjamin Netanyahu and Defense Minister Israel Katz as the leader of Hamas's Qassam Brigades. The strike was the most prominent in a series of operations through the spring.

According to the Gaza Health Ministry, more than 850 people have been killed in Gaza since the ceasefire was reached in October. April was the deadliest month in Gaza since January, with Israeli forces increasing the frequency of operations and the number of violent incidents rising sharply compared with the previous month.

Israeli operations have focused on eastern Gaza City and Khan Younis, areas that have suffered repeated bombardment and displacement throughout the war. Humanitarian organisations describe a worsening environmental and public health crisis, including waste accumulation, sewage contamination and the spread of disease.

Regional spillover

Beyond Gaza, the broader regional picture has remained tense. The Israel Defense Forces issued evacuation orders for a dozen towns in southern Lebanon on May 3, indicating continued Israeli operations against suspected Hezbollah positions. Hezbollah has reportedly deployed a new weapons system designed to evade Israeli detection.

Tensions with Iran, while contained from the spikes of late 2024 and early 2025, remain elevated. Iranian-aligned forces in Iraq, Syria and Yemen continue to engage in periodic exchanges of fire with Israeli forces, U.S. troops and shipping in the Red Sea.

Canada's evolving position

Canada has historically maintained a strong relationship with Israel while supporting the right of Palestinians to a state of their own through a negotiated two-state outcome. The conduct of the war in Gaza has created significant tensions within that framework, with successive Canadian governments adjusting position over the past two years.

Under former Prime Minister Justin Trudeau, Canada moved to limit some arms-export permits and imposed targeted sanctions on settlers. The Carney government has continued that trajectory while engaging with Israeli, Palestinian and regional counterparts at senior levels.

The former diplomats' letter argues that Canada must do more to be consistent with its stated commitment to international humanitarian law. Government officials have stressed the importance of engagement, alliance management and pragmatism, while acknowledging the legitimacy of the underlying concerns.

Domestic political pressure

The issue has been a politically charged one in Canadian domestic politics. Parliamentary motions, public protests and statements by civil society organisations have called for stronger action by the federal government. Pro-Israel and pro-Palestinian voices have both pressed their views, with significant divisions within and across party lines.

The Carney cabinet includes ministers with a range of views on Middle East policy. The Prime Minister has signalled a desire to maintain a careful balance, framed around international humanitarian law, the security of Israeli civilians, the rights of Palestinians and the importance of regional stability.

The Canadian-Arab and Jewish communities

Canada is home to significant Arab and Jewish communities, both of whom have been deeply affected by the war. Demonstrations, vigils and counter-demonstrations have been frequent in cities across the country since October 2023. Reports of antisemitic and Islamophobic incidents have increased.

Federal and provincial governments have invested in security supports for community institutions on both sides and have called for civil discourse. The polarisation of the debate has nonetheless been a feature of Canadian political life through the war.

The campus and civil society dimension

Canadian university campuses have been particularly active sites of debate about the war in Gaza, with student protests, encampments, faculty letters and administrative responses producing significant attention through the past two academic years. Several university administrations have engaged in extended negotiations with student protestors about divestment, transparency in investment policies and academic engagement with Israeli institutions.

Civil society organisations across Canada have organised demonstrations, fundraising drives and advocacy campaigns related to the conflict. Coalitions on both sides of the issue have organised activities in major cities, with periodic flashpoints requiring responses from law enforcement, university administrators and elected officials.

The Canadian Charter of Rights and Freedoms protects freedom of expression and freedom of peaceful assembly, but the application of these rights in the context of charged political demonstrations has been the subject of ongoing legal and political discussion. Federal, provincial and municipal officials have generally emphasised the importance of protecting both rights and ensuring public safety.

The longer-term effects on Canadian campuses, civil society organisations and political discourse will take time to assess. Generations of younger Canadians who have come of age politically during the war are bringing the experience to bear on their broader political views, with implications that extend well beyond the Middle East policy file itself.

Humanitarian assistance

Canada has provided significant humanitarian assistance to Palestinians in Gaza and the West Bank, channelled through UN agencies, Canadian non-governmental organisations and international partners. The flow of aid has been limited by access constraints inside Gaza, including restrictions on crossings and the destruction of distribution infrastructure.

The UN Relief and Works Agency for Palestine Refugees, which has historically been a key partner for Canadian humanitarian funding, has been operating under significant strain. Canada has continued to support the agency while engaging on questions of governance and accountability.

The diplomatic outlook

The pathway to a more durable ceasefire and to broader regional de-escalation remains uncertain. The October 2025 ceasefire, while still nominally in effect, has been so heavily eroded by ongoing operations that humanitarian observers describe Gaza as effectively in a continuing state of conflict.

Talks aimed at expanding the ceasefire, securing the release of remaining hostages and providing the basis for reconstruction have continued in regional capitals, with Egypt, Qatar and the United States playing leading roles. Outcomes have been incremental at best.

Hostages, accountability and reconstruction

The question of hostages held in Gaza, including some with potential ties to Canadian residents and citizens, remains a central element of the broader diplomatic effort. The October 2025 ceasefire included provisions for hostage releases, but a number of hostages have continued to be held, and their families have pressed for renewed efforts to secure their freedom.

Accountability for actions during the conflict has been the subject of significant international legal and diplomatic activity. The International Court of Justice has been considering cases related to the conduct of the war, and the International Criminal Court has issued arrest warrants related to specific individuals. Canada has supported international legal mechanisms while engaging on the specific issues raised by ongoing cases.

Reconstruction in Gaza, when conditions permit it to begin in earnest, will require massive international resources and coordinated planning. Canada has supported preliminary work on reconstruction planning through international partners, while emphasising that durable reconstruction requires a political pathway that addresses the underlying causes of the conflict.

Canadian non-governmental organisations have continued to engage on humanitarian, development and human rights issues across the region. Their work has been complicated by security conditions, funding constraints and access limitations, but represents an important part of the broader Canadian engagement with the region.

What's next

The Carney government is expected to respond to the former diplomats' letter in the coming weeks, including by indicating any new measures it intends to take. Officials have signalled that Canada's approach will continue to be guided by international humanitarian law and by coordination with like-minded allies.

For Canadians watching from a distance, the war's impact is felt through the political debate at home, the work of humanitarian organisations, the experiences of Canadians with family ties to the region, and the broader strain on the rules-based international order. The pressure from former senior diplomats represents a notable escalation in domestic calls for a tougher Canadian posture.

Whether the appeal moves the needle on government policy will become clearer in the weeks and months ahead, as the Carney government weighs its position alongside the demands of allies, the realities on the ground and the views of Canadians across a deeply divided political landscape.
