Whitehorse, YT

Job Type

Full Time, Seasonal


Castle Rock Enterprises has been a market leader in the areas of underground utilities (sewer, water, electrical), site preparation, quarry services, land remediation and trucking for over 25 years. Founded in 1995, the company was purchased by Dakwakada Capital Investments (DCI) in 2010, which has maintained its family-business culture. DCI is a privately owned investment firm in Whitehorse, Yukon that holds and manages most investment and business assets of the Champagne and Aishihik First Nations (CAFN).

On top of its reputation as a top-quality construction company, it includes being a 100% First Nations owned business in its competitive advantage. Castle Rock maintains strong partnerships with the CAFN and the broader Whitehorse and Yukon communities through many community giving and sponsorship programs.

One of the first companies in the Yukon to achieve COR Certification, the health and safety of employees, contractors and the public is an integral part of our daily activities and our most vital core value at Castle Rock.

Established as the Yukon’s capital city in 1953, the City of Whitehorse is home to some of the most spectacular scenery, talented artists and innovative businesses in Canada. Situated along the Yukon River on the traditional territory of the Kwanlin Dün First Nation and the Ta’an Kwäch’än Council, over 33,000 people call Whitehorse home. The City enjoys a healthy economy thanks to a strong business community, which was recognized when Whitehorse was named the top city for entrepreneurs in 2018 by the Canadian Federation of Independent Business. The City also enjoys a successful working relationship with area First Nations and the territorial government.

Environmental sustainability and responsibility has become a key priority for the City. Known as Wilderness City, access to nature remains a top value for residents who can enjoy recreation activities year-round, a vibrant art scene and a multitude of cultures as people from all over the world have decided to settle north of 60.

There is a reason why Whitehorse has seen a steady growth in population; it’s because it truly is a wonderful place to live, work and play. Yukon also boasts excellent health care and education systems as well as many federal and territorial tax incentives that increase the value of your compensation package. This is your opportunity to trade in the noise, congestion and traffic for clean air, open spaces and untouched wilderness while growing your construction industry career.
