In the United States alone, President-elect Barack Obama pitched a tax cut and spending plan that could cost nearly $800 billion and proposed investments in a range of sectors.
"It will take some time for this infrastructure spending to impact company results but investors should anticipate some impact by the end of 2009," Dundee Capital Markets analysts said in a recent research note.
"So how do we Canuck investors play this development?"
A group of Dundee analysts selected seven Canadian stocks it expects to benefit most from investments it sees being made in clean energy and building products, public transit, electricity grid modernization, and broadband telecommunications equipment.
Engineering and architecture firm Stantec Inc has a range of green services that could see a surge in demand, said analyst Richard Stoneman.
Alongside its environmental group, which offers such services as site remediation, Stantec has a building division with broad experience in environmentally friendly construction, the analyst wrote.
Stantec's industrial group is a North American leader in the construction of wind farms and solar projects, while its transportation group is involved in big mass transit projects, he wrote.
Train maker Bombardier is also well positioned, the analyst wrote, with a two-year order backlog as countries around the world expand mass transit systems due to energy and environmental concerns.
High tech company RuggedCom Inc is in "the sweet spot" for any spending plans on intelligent traffic systems, said analyst Arinder Mahal.
It makes networking equipment that helps electrical utilities modernize decades-old power grids. The company has close to 400 utilities as customers and is entering such emerging markets as China and India, Mahal wrote.
Analyst Ian Tharp said that Day4 Energy Inc's modest U.S. operations could get a jump start if that country's incentive plans make solar power installations more affordable. Currently Day4 sells the bulk of its solar modules into higher-priced European markets.
US Geothermal may also benefit, Tharp said. The U.S.-based, Toronto-listed geothermal power developer has operating power plants and exploration projects.
Mahal said that DragonWave Inc could make gains from a spending push for broadband services. It makes microwave communication systems that carriers use to deliver wireless service.
Whitemud Resources could benefit from infrastructure spending, Stoneman wrote. It supplies metakaolin, a supplementary cement material that cuts the cost and generates less carbon dioxide than traditional cement manufacturing.
