Hundreds of demonstrators arrived at Calgary's Municipal Plaza on Sunday to bring attention to the many concerns they feel world leaders need to grapple with when they meet in Kananaskis, Alta., over the next three days.

In 2018, the president called for the group to embrace Russia and stormed out of the summit. Now he is seeking to shrink America’s military role abroad and embarking on a more expansive trade war.

As the leaders were scheduled to arrive Sunday hundreds of protesters from several different groups rallied in front of Calgary City Hall, with many carrying anti-Trump messages.

The news is about to be flooded with the latest from the Group of Seven as some of the world's most powerful leaders travel to the Canadian Rockies next week for high-level meetings on major issues.

Premier Danielle Smith says the G7 Leaders’ Summit is an opportunity to promote Alberta’s energy ambitions to an eager international audience. Smith, who met with Pete Hoekstra, the U.S. Ambassador to Canada, in Calgary on Saturday, will greet leaders from G7 and non-member nations when they arrive in the city Sunday.

Britain and Canada have deep ties in defence, climate and culture sectors, but Starmer's visit comes amid strained trade negotiations.

Given its power, the G7 is a target for advocates on a range of issues who hope to see their priorities reflected in the communiqué. Ottawa has faced calls to speak out against arbitrary detainment, Africa's debt crisis and Pakistan's Kashmir dispute with India.

Alberta Premier Danielle Smith says she likes the federal government’s plan to reduce the approval times of major infrastructure projects down to two years, and she hopes Canada can revise other legislation to "improve investor confidence.
