Bish is right. My mistake. The Canadian Lanc is scheduled to depart Hamilton, in Canada on August 4 flying over the North Atlantic stopping at Goose Bay in Labrador, Narsarsuaq in Greenland and Keflavik, Iceland before flying the final leg into Coningsby on August 8th. They're allowing themselves 4 days to complete their journey to England in case they run into bad weather.
According to the article, following a short period of maintenance & training flights, the Canadian Lanc will operate from August 14 along side with the other Lancaster in a series of airshows, the dates of which will be confirmed soon.
