British Prime Minister Theresa May has expressed her condolences to the family of a Canadian woman who was killed in the weekend terror attack in London. Thirty-year-old social worker Christine Archibald was struck by a speeding van that plowed into crowds of people strolling on London Bridge on Saturday. Archibald’s family in Castlegar has released a statement asking people to honour her memory by volunteering or donating to a homeless shelter. Both May and Prime Minister Justin Trudeau are praising the family’s generosity in encouraging community service despite the tragedy they have experienced.
