“We’re going to work with the provinces and territories to try to see that we’re aligned on this,” Trudeau said at a news conference in New Brunswick on Tuesday. “There are still some details to be worked out, but the statement of opportunity for Canadians to mourn on Monday will be significant.” “Therefore, on our part, we will inform federal employees that Monday will be a day of mourning,” he added. Trudeau said the federal government is in discussions with the U.K. government and the offices of opposition leaders to determine who will make up the delegation of Canadian officials traveling to the queen’s funeral. Other Commonwealth countries have already announced public holidays to mark the Queen’s death: the UK will have a public holiday on Monday for the funeral, marking the last day of 10 days of mourning, and Australia and New Zealand will have public holidays on September 22 and 26 respectively. Canada is still in the midst of its official period of mourning for the country’s longest-reigning monarch, with several memorial events planned in Ottawa after the funeral on Monday. A memorial service will be held at Christ Church Cathedral, with government officials, dignitaries and other guests, as well as a parade with the Canadian Armed Forces and RCMP, a 96-gun salute and a CF-18 fighter jet fly-by. Leader of the House of Commons Mark Holland tweeted on Saturday that a “special sitting” of the House of Commons would be held on Thursday to give MPs a chance to pay tribute to Queen Elizabeth II. Canada’s parliament was due to resume on September 19, but it had already been delayed a day for the Queen’s funeral. With files from CTVNews.ca’s Tom Yun and Rachel Aiello
