Keeping ahead of covid-19

This rapidly evolving coronavirus (covid-19) has imposed an unsettling, fluid situation upon our community and its businesses. While the team here at THE MARINE TECK still aims to maintain a “business as usual” approach, we are making a number of significant changes to our operation to account for a situation that is far from normal.
