Shannon Park is located in Dartmouth, Nova Scotia, across the bay from Halifax. It is the the site of a former military housing complex. Environmental studies show that the site is contaminated with approximately 24,000 tonnes of soil containing arsenic and hydrocarbons.

The site has been empty since 2003. In 2014, it was purchased by Canada Lands Company, a federal crown corporation. In 2017, all buildings on the site were demolished.

In November 2018, the federal government issued tender documents for remediation of the site with the goal of it being cleaned up by the spring of 2019.

In December, it was announced that Dexter Construction Company Ltd. was recently awarded a contract to excavate, transport, and dispose of the contaminated soil from the Shannon Park site. They are also required to backfill the excavated area with clean fill as part of the contract. The value of contract is $900,933.

Dexter Construction, located in nearby Bedford, is the largest civil contractor in Nova Scotia with over 40 years of experience in infrastructure, mining, and the environment. Dexter Construction Company Limited is a subsidiary of Municipal Enterprises Limited and is the construction arm of the Municipal Group of Companies.

Previous environmental projects that Dexter Construction has been involved with include the Halifax Regional Municipality landfill development and the Halifax Harbour sewage treatment system construction.

With respect to the site being the home to a new stadium for the Halifax Schooners of the Canadian Football League, there is much to be done including the football team purchasing the land, raising $200 million to build the stadium, and getting approval for construction.
