No problem at all.
And agreed. York's School of Social Work gets anywhere from 800-1000 applications, and they take only 20 for their 2-Year Program, and under 60 for their 1-Year Program. It's also the only school that offers guaranteed funding, and if you get into the program as a full-time student, your tuition and books are pretty much covered completely.
Given that York's School of Social Work does not have a strong focus on clinical social work, I would advise against gearing your application towards that. I recommend those interested in clinical social work apply to UofT (since it has a clinical stream). I would also advise against listing/citing work experience from several different workplaces in different areas of social work. This can be viewed as the applicant not having a strong idea of what he/she/they hope to do in the future.
DO ensure that your passion for social work and social change comes through. DO makes full use of the Supplementary Information Form and include the names of the professors you would like to work with. This would seem odd given that most of you haven't attended York, but it would definitely impress the committee if you did research on particular professors we have here that specialize in areas you're interested in. Then, list these professors on your Supplementary Information Form with perhaps a small blurb as to why you chose them and what you admire about them.
I hope this helps! Let me know if you have any further questions.
