I live in Canada, but work in the United States ( I own my own small business and located it in Niagara falls, ny to save money).Unfortunately some of my suppliers require a credit card but wont accept a Canadian one, as my products are shipped to my location in Usa.How can a find a bank that will issue me a Usa credit card and bank account, so I can do local business?

I believe if you go to a Bank of America, they would be more than happy to issue you a card. They are doing it for illegals and require no ID.

Go into a major American bank that is also a credit card issuer. Explain your situation to them. Many are more than happy to help out people doing business in their country. The credit card would be under the business's name which is domiciled in the States so I can't see them giving you a hard time.

go get a green card for a citizenship and you can get one
