CALGARY, Alberta (Reuters) - The sudden surge north of the massive wildfire burning in Canada's oil sands region has dealt a new setback to producers, triggering a second round of evacuations and threatening work camps north of Fort McMurray.

With the city of Fort McMurray off limits and fewer places to house workers needed to restart operations, production may be shut down for longer than companies and market analysts had anticipated.
