Many businesses, institutions, and organizations from coast to coast (to, say it with us now—coast) are closed today for the Canada Day long-weekend. And after a day or two to recover from the celebrations around the pinnacle of Canada's 150th birthday, Parliamentarians, politicos, and the private sector are back at it tomorrow. Here's a rundown of what's on the agenda for Tuesday, July 4. Happening around the Hill: Ambassador of Saudi Arabia Naif Alsudairy is holding a press conference with the Ambassador of the United Arab Emirates, Mohammed Shehhi, and the Egyptian Ambassador, Motaz Zahran, at the Saudi Arabian embassy in Ottawa at 12:30 p.m. to discuss the diplomatic situation between a number of Gulf nations and Qatar. A number of countries like Saudi Arabia, the United Arab Emirates, Egypt, Bahrain, and Yemen have ended diplomatic relations with Qatar, accusing the country of harbouring terrorists and being too closely connected with Iran. Qatar's foreign ministry has said the allegations "have no basis in fact." Nationwide news-makers: François-Philippe Champagne, minister of International Trade, and Brian Gallant, premier of New Brunswick, will be in Saint John N.B. to announce a major pan-Atlantic trade and investment initiative. The event will take place at 1 p.m. at the Diamond Jubilee Cruise Terminal. Sherry Romanado, parliamentary secretary to the minister of Veterans Affairs and associate minister of National Defence, will be in St. John's Nfld. to hold meetings with Canadian Forces Members and their families to discuss the contents of the 2017 federal budget, and its implications and policies for military members, veterans, and their families. The meetings will take place at the Military Family Resource Centre at 10 a.m. Amarjeet Sohi, minister of Infrastructure and Communities, will be in Lethbridge, Alberta with Maria Fitzpatrick, MLA for Lethbridge-East; Lethbridge Mayor Chris Spearman; and Reeve Lorne Hickey, from Lethbridge County to make an infrastructure announcement at City Hall. The event will take place at 10:15 a.m. Carolyn Bennett, minister of Indigenous and Northern Affairs, will be at the Alexis Nakota Sioux Nation Band Office in Glenevis, AB today to announce the construction of a pump house, treated reservoir, and waterline, which will connect Alexis Nakota Sioux Nation to the West Inter-Lake District supply system. She will be joined at the event, which is taking place at 10:30 a.m., by Richard Feehan, Alberta's minister of Indigenous Relations, and Chief Tony Alexis. Stay on top of the world: Prime Minister Justin Trudeau will be in Dublin, Ireland before heading to Edinburgh, Scotland, on Wednesday. According to a press release, while in Dublin, Mr. Trudeau will meet with the Irish taoiseach (similar to a prime minister) Leo Varadkar for the first time. The two leaders will discuss bilateral affairs, and possible benefits of the new Canada-European Union Comprehensive Economic and Trade Agreement (CETA). While in Edinburgh, Mr. Trudeau will have a private audience with Queen Elizabeth II at the Palace of Holyroodhouse. Later this week, Mr. Trudeau will attend the G20 Summit in Hamburg, Germany. Marie-Claude Bibeau, minister of International Development and La Francophonie, will be in the Democratic Republic of Congo (DRC) and Ghana until July 9, 2017. According to a press release from Ms. Bibeau's office, while in the DRC, she will be focusing on ways that Canada can work with local and multilateral partners to "advance the rights of women and girls, including peace and security, access to sexual and reproductive health services and the reduction of sexual and gender-based violence." While in Ghana, Ms. Bibeau will be accompanied by Right To Play ambassadors Kaylyn Kyle—who won a bronze medal as part of the Canadian soccer team at the London 2012 Olympics—and Joannie Rochette, a Canadian figure skater who won bronze at the 2010 Vancouver Olympic Games. The group will tour Right To Play projects, which work to remove barriers to education and to encourage play-based learning—especially for girls.
