The Domtar mill in Dryden is getting some extensive work done to it. The 22.7 million dollars worth of improvements were announced by Prime Minister Stephen Harper on a visit to the community on Saturday. It will allow the mill to produce it's own renewable energy and reduce the amount of power it buys from more expensive sources. Prior to the announcement Harper spent time at the Dryden Air Show which starred Canada's own aerobatic air team the Snowbirds.
