OTTAWA — Prime Minister Justin Trudeau condemned Tuesday's attacks in Brussels, as his cabinet ministers said they saw no imminent threats to Canadians on their soil. "I was outraged when I woke up to the news that so many innocent citizens had been killed and injured — shocked and profoundly saddened," Trudeau said after a cabinet meeting on Parliament Hill. "This cannot and will not be tolerated."

I strongly condemn today's deplorable terrorist attacks in Brussels. My thoughts are with the victims as we stand with Belgium & the EU. — Justin Trudeau (@JustinTrudeau) March 22, 2016

Trudeau, Public Safety Minister Ralph Goodale and Foreign Minister Stephane Dion pledged solidarity with Belgium, the European Union and victims of the bombings. Dion called it a "black Tuesday" for Belgium, as support reverberated across Canada with the premiers of Alberta and Saskatchewan expressing their support. "Hearing the screams of children in the smoke of the Brussels Metro only strengthens our resolve to combat terrorism in all its forms, and increases our solidarity with the people of Belgium and the whole of Europe," Dion said. Goodale said the national threat level will not be changed from medium, where it's been since October 2014, when two Canadian soldiers were killed in separate attacks at the National War Memorial in Ottawa and in Saint-Jean-sur-Richelieu, Que. "There is no information available to RCMP or CSIS that would lead us to any change in threat levels," he said. Canadian embassy monitoring Nevertheless, security on Parliament Hill appeared to be heavier than usual. A visiting European politician called for a moment of silence on Parliament Hill at the start of a news conference. "Today is not really a happy day for the European Union and I think for many people worldwide," said German Social Democrat Bernd Lange, chair of the European Parliament's trade committee. Lange was leading a delegation to Ottawa to study the effects of the massive Canada-EU free-trade deal, which is expected to come into effect early next year. Artis Pabriks, the EU's rapporteur on the deal, said while good intelligence and co-operation between allies are essential for preventing terrorist attacks, Europe, Canada and the United States need to do more on that front. "Violence and naked power should not be, and will not be the thing which will determine how we will live," said Pabriks, Latvia's former defence minister. "So we have to stand up to this — and we have to stand up together." Goodale also reminded Canadians to be vigilant.

If you notice anything that you consider to be unusual or out of the ordinary then you should report that circumstance immediately to your local police," he said. Dion said he has "no reports of any Canadian citizens being affected by the incidents." Interim Conservative Leader Rona Ambrose said the attacks reinforce "our resolve as Canadians to stand up to this scourge." Belgian officials said the casualty toll from three explosions in the capital was 31 dead and 187 injured. Belgian Health Minister Maggie de Block said 11 people were dead and 81 injured in twin explosions at the Brussels airport. The Brussels mayor said at least 20 people died and 106 were injured in the attack on the Maelbeek subway station, which is close to the European Union headquarters. The Islamic State group claimed responsibility for the attacks in Brussels, saying its extremists opened fire in the airport and "several of them" detonated suicide belts. In an advisory posted on its website early Tuesday, Global Affairs said while there was no nationwide advisory in effect for Belgium, Canadians should exercise a "high degree of caution due to the current elevated threat of terrorism." Air Canada also warned that flights to the Belgian city may be cancelled and security was beefed up at one of Toronto's main transportation hubs. At least one Twitter post indicated the cancellation of a Canadian school trip to the European capital.
