On Sunday, Ms Freeland also held a meeting with female foreign ministers from non-G7 countries - TV cameras captured her riding her bicycle there from the brunch - and announced Canada would host the world's female foreign ministers for a conference in September.
The two-day meeting also discussed tensions with Iran and North Korea, while also addressing political problems in Venezuela and Myanmar.
The gathering comes days after North Korea pledged to suspend testing of its nuclear and long-range missiles and close its nuclear test site, and days ahead of this week's historic summit between North Korean leader Kim Jong Un and South Korean President Moon Jae-in.
Mr Trump is also working on his own landmark meeting with the North Korean leader in the coming weeks, after dispatching Central Intelligence Agency director Mike Pompeo on a secret mission to meet with Mr Kim two weeks ago to set the table.
With Trump threatening to withdraw the United States if an agreement to revamp the deal can not be reached before the May 12 deadline set by the USA leader, Kono said "many ministers" sought "continuous and complete implementation" of the deal.
France's President Emmanuel Macron, who begins a series of meetings with Trump on Monday, said in an interview that the West must stand up to Putin's attacks on western democracy, including the spreading of "fake news".
Even the global and interior ministries are holding discussions by which Chrystia Freeland has pushed Russian Federation on the peak of a crowded schedule which features the ongoing crisis, Iran along with North Korea. Trump has nominated Pompeo as his next secretary of state, but he isn't in Toronto because he continues to face opposition to his confirmation.
Acting U.S. Secretary of State John Sullivan called on Moscow to stop creating impediments to peace in Syria and to play a role in ending the seven-year-long conflict.
Freeland made no public comment on North Korea as she opened Sunday's talks at the University of Toronto. The guests met with the Minister of foreign Affairs of Canada Christina Freeland.
"Fundamentally, Ukraine is perceived by many and also by Russia as a sort of test range for testing Russian nonconventional warfare - hybrid war", Klimkin said.
The G7s foreign and interior ministries are holding talks in Toronto, where Chrystia Freeland, Canada's foreign affairs minister, has pushed Russian Federation to the top of a packed agenda that includes North Korea, Iran and the ongoing Syrian crisis.
The foreign ministers' talks, due to end late on Monday, will help prepare for a G-7 leaders' summit in Canada in early June.
"We don t want to see that outcome, but plainly a lot of thought is going into how to keep a non-US version of the JCPOA", he said.
