I need help about information about dermatologists in Canada?

So I'm writing this question today is because I have horrible acne on my face and back lately, I feel like I should go to the dermatologist to try to cure my acne. I tried many store acne products and they would work for a while then stop working so I feel like going to the dermatologists is my last option.Do you believe going to the dermatologist is worth it? I'm also wondeirng does the dermatologist clinics is free medical care like walk in doctors and family doctors? ( I live in Canada) or do I have to pay every time I vistied like the denists I have more questions but can someone just answer the two I have right now thank you.
