Mr. Trudeau's office strongly denied any wrongdoing on the part of the prime minister, who is an outspoken feminist and had put gender equality and women's empowerment near the top of the issues he hoped to promote during the summit meeting.
Canadian Foreign Minister Chrystia Freeland said the Russian Federation issue "hasn't been raised around the G-7 table", though she said there have been "some direct conversations in bilateral meetings".
Canadian Prime Minister Justin Trudeau said the leaders would air their unhappiness in what he called a polite cordial context and expressed optimism about the summit.
"Russia is focused on other formats, apart from the G7", Kremlin spokesman Dmitry Peskov said in a brief statement reported by the Government-controlled Sputnik news agency.
Departing the White House for a fractious summit with European, Canadian and Japanese leaders, Trump said their 2014 decision to suspend Russian Federation from the group of the world's most advanced economies - after Moscow annexed Ukraine's Crimea region - should be reversed.
"The American President may not mind being isolated, but neither do we mind signing a six country agreement if need be", Macron tweeted in English, turning to the medium Trump has made his own.
Mr. Macron, feuding with Mr. Trump over US steel and aluminum tariffs on the European Union, tweeted that he and the other six leaders were prepared to turn their backs on Mr. Trump at the summit.
Earlier in Ottawa, Macron and Trudeau offered an olive branch of sorts by offering Trump a modest measure of support in his historic meeting in Singapore with North Korean leader Kim Jong Un following the G7 summit.

For his part, Trudeau has expressed his displeasure over the tariffs (which were invoked citing national security) saying that Canada and the USA have had a great relationship over the years. The White House then announced Trump would skip some of the G-7 sessions.
Even before these developments it had become clear that this would be one of the more contentious G-7 meetings in memory. Then he pulled the US out of the Paris accord the following week. Other leaders have since retaliated with their own tariffs on American goods.
"We're going to deal with the unfair trade practices".
Relations have hit such a low point that a key question now is whether the seven countries can agree on a joint statement of priorities at the conclusion of the meeting.
U.S. trading partners have been furious over President Donald Trump's decision last week to impose tariffs on steel and aluminium imports from Canada, the European Union and Mexico as part of his "America First" agenda.
The body language as Mr. Trump first met the other leaders looked a little strained, but there were still smiles.
Mr. Trump answered with a claim that - quote - "The E.U. trade surplus with the U.S.is $151 billion". Salvini and fellow euro-skeptic coalition partner Luigi Di Maio, of the 5-Star Movement, agreed to back Conte so their parties could govern.
