Michael Kovrig, the former diplomat, and a second Canadian, Michael Spavor, were taken into custody earlier in the week after a top Chinese tech executive was arrested in Vancouver at the request of the United States.
Canada's foreign ministry said its ambassador to Beijing, John McCallum, was granted consular access to Kovrig and is pressing for access to Spavor. Speaking to The Canadian Press, Prime Minister Justin Trudeau predicted that access would take place "shortly."
"We are being absolutely clear on standing up for our citizens who have been detained, trying to figure out why, trying to work with China to demonstrate that this not acceptable," he told Citytv in Toronto.
Meanwhile in Washington, Canada's foreign and defense ministers held talks with their US counterparts on the row.
The Canadians were arrested for what China has said is suspicion of "harm to national security" -- a phrase often used by Beijing when alleging espionage.
But the detentions are widely believed to be retaliation for Canada's arrest December 1 of Meng Wanzhou, the chief financial officer of Chinese telecom giant Huawei.
Meng was arrested while changing planes in Vancouver, outraging China and sparking a diplomatic standoff between the North American allies and Beijing.
"This is one of the situations you get in when the two largest economies in the world, China and the United States, start picking a fight with each other," Trudeau said.
"The escalating trade war between them is going to have all sorts of unintended consequences for Canada, potentially the entire global economy. We're very worried about that."
The United States has accused her of lying to bankers about the use of a covert subsidiary to sell to Iran in breach of sanctions. If convicted, she faces more than 30 years in prison.
On Tuesday, a Canadian judge ordered Meng's release on Can$10 million ($7.5 million US) bail, pending a US extradition hearing.
- Visit shelved -
Canadian Tourism Minister Melanie Joly, meanwhile, shelved a trip to China next week to promote tourism.
Since Beijing approved Canada as a tourist destination for its citizens in 2010, the number of Chinese tourists visiting Canada has risen by 20 percent per year to almost 700,000 in 2017.
Ottawa had hoped to double the figure by 2021, opening seven new visa application offices in China this year to facilitate the processing of travel documents. But those targets are now in doubt amid a public backlash in China.
Kovrig, who works for the International Crisis Group (ICG) think tank, was being investigated by the Beijing bureau of state security, while the agency's office in northeastern Liaoning province was handling the probe into Spavor, Lu said.
Spavor is a China-based business consultant who facilitates trips to North Korea, met with its leader Kim Jong Un and arranged some of retired NBA star Dennis Rodman's trips to the country.
China's foreign ministry said ICG was not registered in China and its employees would be "in violation" of the law if they engage in activities in the country.
ICG closed its office in the Chinese capital after Beijing passed a law on NGOs, which came into force in 2017, to better control the activities on its soil of foreign organizations.
Kovrig was based in Hong Kong for ICG, working on foreign policy and security issues in the region, particularly on the Korean Peninsula.
