Ontario DECA

In just 40 years, Ontario has grown to be the largest DECA association in the world. In this time, we have built our networks of members, alumni, educators, school administrators, and business professionals, creating a community of growth and mentorship. DECA’s programmes and activities have innovated over time offering opportunities to explore new career paths and technologies as they apply to the world of work. Our membership has organically grown by 20% in the past year – a testament to our ability to meet the demand by youth for experiential learning.
