It's a record year in Canada for the number of good quality beaches and marinas and Colchester Harbour Marina in Essex is among the best.
27 beaches and nine marinas have received the 'Blue Flag' which is the international gold-standard for water quality, environmental management and education, safety and amenities.
The local beach received the recognition in 2017 and again this year.
The blue flag is administered in Canada by Environmental Defence.
More than 4,000 beaches and marinas in 45 countries fly the blue flag.
