The Gulf Islands enjoy Canada’s mildest climate with cool wet winters and warm dry summers. The area is home to large numbers of artists, trees, marine life and spectacular scenery. The Gulf Islands School District has ten schools, seven of which are on Salt Spring Island. The School Board office is located in Ganges, also on Salt Spring. Just over 600 students attend Gulf Islands Secondary, the District’s largest school. The other schools are smaller, one with as few as 6 to 12 students.
