(Adds Imperial oil operations restart) May 24 (Reuters) - Oil companies are restarting operations and evacuation orders for work camps are being lifted near Fort McMurray, Alberta, as wildfires burning around the Canadian oil sands hub for most of May have stopped growing, officials said. The shutdown at major oil sites as a result of the wildfires has cut daily production by more than 1 million barrels, officials said. About half of the nation's oil sands capacity remains shut, according to Reuters calculations. The fires now cover about 500,000 hectares (1,930 square miles). Camps near Nexen's Long Lake and ConocoPhillips's Surmont facilities, both of which had stopped production due to the fires, were cleared to reopen, along with camps near Enbridge Inc's Cheecham terminal, which the company has said was returning to full service.
