0namesleft3, there's at least 1 shop on etsy that sells oilcloth:
http://www.etsy.com/shop/oilclothaddictShe's local to me and very good.

I'm sure she's very good, but the question was about CPSIA compliance, and sadly, oilcloth is not compliant. I have seen it in the stores (at Target on chalk-mats) so someone must make something similar, but generally it's not compliant.
This is a note from her shop:
Please note that the recent Consumer Product Safety Improvement Act of 2008 (CPSIA) prohibits oilcloth garments such as bibs and aprons or toys for children. While there are no heavy metals in oilcloth, it does contain Phthalates, which softens the plastic coating used to manufacture Oilcloth.
