I believe they recently changed owners and this place used to be called Nails and Me, but is now call Rachel's Nail Art.
They have an excellent selection of OPI, Essie, Orly and China Glaze polishes in addition to the usual Shellac options. This place is clean and relaxing, the staff are friendly and very thorough. Don't come here if you're in a rush because the staff really take their time on you, which is refreshing from most other nail salons that rush you out. Very reasonably priced and one of the best nail salons I've tried in the Thornhill area.
