Ukrainian President Volodymyr Zelenskiy on Friday makes his first visit to close ally Canada, where he is guaranteed a warmer welcome than he received from some U.S. politicians skeptical about providing more military aid.

Canada is one of Kyiv’s staunchest supporters in its war with Russia, and is set to announce during the visit that it is sending more weapons to Ukraine, according to a government official.

“Canada remains unwavering in our support to the people of Ukraine as they fight for their sovereignty and their democracy, as well as our shared values like respect for the rule of law, freedom, and self-determination,” Prime Minister Justin Trudeau said in a statement late on Thursday.

Zelenskiy is due to address parliament in Ottawa at 1 p.m. ET (1700 GMT) and then hold a news conference with Trudeau at 2:45 pm ET (1845 GMT) before flying to Toronto to meet business leaders and then address a rally.

The Ukrainian leader said he would be talking to Trudeau about defense cooperation, and would sign treaties to strengthen economic ties.

“I am certain this will be a meaningful visit. We are grateful to Canada for its principled leadership and support,” Zelenskiy said in a post on messaging platform X, formerly known as Twitter.

Dozens of extra police were on duty on Friday in central Ottawa, and roads leading to Parliament Hill were blocked off.

The Communications Security Establishment, Canada’s signals intelligence agency, warned the cybersecurity community against malicious threats.

“It’s not uncommon to see increased distributed denial-of-service campaigns against NATO countries that support Ukraine, or host visits from Ukrainian government officials,” it said in a statement.

There are 1.4 million people of Ukrainian descent in Canada, the third most after Ukraine and Russia.

Ihor Michalchyshyn, executive director of the Ukrainian Canadian Congress lobby group, said Canada was influential given its membership in both the Group of Seven leading industrial countries and NATO and noted all Canadian political parties support Ukraine.

“So I think it’s appropriate for the president to be expecting and asking more from his Canadian partners,” Michalchyshyn said in an interview. “If friends of Ukraine want Ukraine to win the war, then the only way that happens is with renewed and more military support.”

In Washington, Zelenskiy appealed to U.S. lawmakers on Thursday for continued support amid doubts by some Republicans over whether Congress should approve a new round of aid.

Although there are no such divisions in Canada, it does not have the deep pockets or military reserves of the United States, Germany and other major backers.

Since the beginning of 2022, Canada has committed over C$8 billion ($5.9 billion) in aid to Ukraine, including over C$1.8 billion in military assistance.

The Canadian government official said the arms deal Trudeau was likely to announce on Friday would be bigger than the C$33 million Ottawa unveiled on Sunday to help Kyiv buy missile defenses. The official requested anonymity because the final details had not yet been agreed.
