I enrolled in the Queen's Commerce bootcamp last year and it helped tremendously in my application. Seeing successful past essays, getting a recommended "structure" for your essays, and learning past strategies for success makes a huge difference in gaining acceptance. The bootcamp modules also help you develop you as a person and encourages self-awareness, strengthening your application as a whole as well. It played an integral role in my acceptance to Queen's Commerce, and I would highly recommend it to those who are serious about their applications to the program.
