On April 25, 2007, the duo announced that they would embark on a tour of Canada, performing in all 10 provinces, plus Yukon, Nunavut and Northwest Territories. In the words of Jack: "Having never done a tour of Canada, Meg and I thought it was high time to go whole hog. We want to take this tour to the far reaches of the Canadian landscape. From the ocean to the permafrost. The best way for us to do that is ensure that we perform in every province and territory in the country, from the Yukon to Prince Edward Island. Another special moment of this tour is the show which will occur in Glace Bay, Nova Scotia on July 14, the White Stripes' Tenth Anniversary." Canadian fiddler Ashley MacIsaac opened for the band at the Glace Bay show; earlier in 2007, MacIsaac and Jack had discovered that they were distantly related. It was also at this time that White learned he was related to Canadian fiddle player Natalie MacMaster.
