Ukraine and Russia keep fighting after three-day ceasefire collapses, leaving Canada's continued support in focus

The three-day ceasefire between Russia and Ukraine announced by U.S. President Donald Trump on May 8 has unravelled into renewed fighting along the eastern front, leaving Kyiv pushing for a longer truce and pressing Western partners, including Canada, to sustain weapons deliveries and financial support. Russian forces have resumed kinetic operations against Ukrainian energy infrastructure and tactical positions in the Donetsk region, despite Trump's continued assertion that the brief ceasefire had been a step toward a broader settlement.

For Canada, the unraveling underscores the gap between the public narrative coming out of Washington and the operational reality of the war as Ukrainian forces and their European backers see it. Defence Minister Bill Blair has reiterated this week that Canada's support for Ukraine remains in place, with the next tranche of artillery shells, anti-armour weapons, and air-defence components scheduled to ship in the coming weeks. The Canadian training mission in the United Kingdom and in Poland, which has trained more than 40,000 Ukrainian soldiers since 2022 under Operation Unifier, continues at planned tempo.

Prime Minister Mark Carney addressed the war briefly in his remarks to reporters on Thursday, framing continued Canadian support as both a matter of European security and a Canadian interest. The prime minister also confirmed that Canada will not adjust its position on frozen Russian assets, which Ottawa has been working with the European Union and the United Kingdom to convert into financing for Ukrainian reconstruction.

How the ceasefire fell apart

Trump's May 8 announcement, which framed itself as a personal achievement of the president, included a 1,000-for-1,000 prisoner exchange and a 72-hour suspension of all kinetic activity to coincide with Russia's Victory Day commemorations. The president said both Vladimir Putin and Volodymyr Zelensky had agreed to the terms. Within hours of the ceasefire taking effect on May 9, Ukrainian officials reported multiple Russian strikes and ceasefire violations, with Zelensky's office documenting more than 700 incidents through the three-day window.

The Ukrainian position, as articulated by Zelensky in a televised address on May 10, was that Russia had used the ceasefire announcement to score a propaganda win during the Victory Day commemorations while continuing operational activity on the ground. Ukrainian officials privately briefed European counterparts that the ceasefire had been worth taking because of the prisoner exchange but that the underlying military picture had not changed.

The prisoner exchange itself was the most concrete element of the three-day pause and was completed on May 11, with 1,000 Ukrainian prisoners released by Russia in exchange for 1,000 Russian prisoners held by Ukraine. The exchange was facilitated through the International Committee of the Red Cross and was the largest single prisoner swap of the war.

Where the war stands

The front line in eastern Ukraine has been largely static for months, with Russian forces making incremental gains in the Donetsk and Luhansk regions at high cost in equipment and personnel. Ukrainian forces have held defensive positions along well-prepared lines, with significant reliance on Western-supplied long-range artillery, anti-armour weapons, and air-defence systems. The pattern is one of attritional warfare in which neither side has been able to produce a decisive breakthrough.

The air war has shifted in Ukraine's favour over the past year as Western air defence deliveries have stabilised the situation around major cities. Russian missile and drone strikes on energy infrastructure continue, but the intensity and the success rate against well-defended targets have declined. Ukraine has also significantly expanded its own long-range drone capability, with strikes deep inside Russian territory becoming a routine feature of the war.

The naval picture in the Black Sea has shifted dramatically in Ukraine's favour over the past 18 months. The Russian Black Sea Fleet has been pushed out of Sevastopol and operates primarily from Novorossiysk. Ukrainian sea drones have repeatedly demonstrated their ability to strike Russian naval assets, and Ukrainian grain exports have largely resumed under the protection of a network of allied naval cooperation that does not yet have a formal framework.

Ukraine's long-term ceasefire proposal

Following Putin's initial two-day Victory Day truce proposal and Trump's three-day extension, Zelensky's office has continued to push for a 30-day ceasefire that would create a window for serious negotiations on a longer-term political settlement. The Ukrainian position is that a 30-day pause would allow time for negotiations on the broader political framework, including the future of occupied territories, security guarantees, and the timeline for any Russian withdrawal.

The Russian position has been that any longer ceasefire must include Ukrainian commitments not to receive new Western weapons during the pause, a condition that Kyiv and its Western backers have categorically rejected. The disagreement has been at the heart of the difficulty in moving beyond short tactical pauses to anything resembling a structured negotiation.

European partners, including France, Germany, the United Kingdom, and Italy, have been working in close coordination with Kyiv on the Ukrainian negotiating position. Canada has been part of those consultations through the so-called Ramstein format, the coalition of supporting countries that has been meeting at least monthly since early 2022 to coordinate military assistance.

The Canadian contribution

Canada has provided more than 19 billion dollars in military, financial, humanitarian, and developmental support to Ukraine since the full-scale invasion began in February 2022. The military component has included artillery, anti-armour weapons, air defence components, armoured vehicles, and ammunition. The Operation Unifier training mission has been one of the largest single national contributions to Ukrainian military capacity building.

The Carney government has confirmed that Canadian support will continue through at least the next two fiscal years, with a multi-year financial commitment laid out in the spring budget. Defence Minister Bill Blair has been in regular contact with his Ukrainian counterpart, Defence Minister Denys Shmyhal, and the bilateral relationship at the working level remains intense.

Canada has also been a leading voice within the G7 on the question of converting frozen Russian sovereign assets into financing for Ukraine. The mechanism agreed at the 2024 G7 summit, which uses the interest on the frozen assets to finance a U.S. and European loan to Ukraine, is now operating. Conversations on the next stage of the framework, which could involve using the principal of the frozen assets, are ongoing among finance ministers and central bank governors.

The Trump administration's position

The Trump administration's posture on Ukraine has remained ambiguous through the spring. The president has framed the war as a foreign-led conflict that the United States should not be paying to support, but the practical record of his administration has included continued delivery of weapons originally authorised under the Biden administration and modest new commitments through the U.S. defence budget. The administration has been pressing Ukraine to accept territorial losses in the east as part of any settlement, a position Kyiv has consistently rejected.

U.S. military aid deliveries have continued but at a slower pace than under the previous administration. Several major systems, including the Patriot air defence batteries and the M777 howitzers, are still being shipped from U.S. stockpiles. Some critical munitions have been delayed by what U.S. defence officials describe as production-related bottlenecks.

The European and Canadian response has been to step up to fill the gap. The European Union's defence industrial strategy, finalised earlier this year, includes a significant component aimed at scaling up European production of artillery shells and other consumables. Canada has been participating in European Union industrial discussions through the strategic partnership agreement that the prime minister signed shortly after taking office.

The Ukrainian diaspora in Canada

Canada has the second-largest Ukrainian diaspora in the world after Russia, with roughly 1.4 million Canadians claiming Ukrainian ancestry. The community has been a consistent voice for continued Canadian support and has provided significant volunteer contributions to humanitarian programmes inside Ukraine. Major diaspora organisations have welcomed the Carney government's confirmation of multi-year support but have continued to press for additional commitments on long-range weapons and on the conversion of frozen Russian assets.

Canada has also been one of the major destinations for Ukrainians fleeing the war, with roughly 300,000 Ukrainians admitted under the Canada-Ukraine Authorisation for Emergency Travel programme since 2022. The programme is winding down its new applications phase, but the existing arrivals continue to integrate into Canadian communities across the country. Provincial governments have been working with the federal government on settlement, language training, and credential recognition.

For Canadian Ukrainians, the recurring cycle of ceasefire announcements that fail to translate into a durable pause is a familiar pattern. Diaspora leaders have repeatedly cautioned Western audiences not to take Russian commitments at face value, citing the long history of failed agreements going back to the 1990s. The collapse of the Trump-brokered three-day ceasefire is being read by the community as a confirmation of those warnings.

What's next

The Ramstein format meeting scheduled for next month will be the next major moment for coordination among supporting countries. Defence ministers from more than 50 nations are expected to attend, with the agenda focusing on weapons deliveries, training, and the longer-term industrial strategy. Canada will be represented at the political level by Minister Blair.

The G7 summit at Kananaskis in June will bring the leaders of the major supporting countries together with Prime Minister Carney as host. Ukraine support and the question of Russian frozen assets are expected to be among the most-watched agenda items. Zelensky has been invited as a partner leader.

For the war itself, the most likely near-term trajectory is continued attritional combat along the front line, continued strikes on infrastructure, and continued political pressure on Western partners to manage the costs of support. The Trump administration's attempts to broker short pauses are likely to continue, with diminishing returns as both sides settle into the rhythm of partial truces that produce limited operational change. The Canadian Wire will continue to report on the war and on Canadian engagement.
