As an AI language model, I assume that you meant "ultramr" as Ultramar, a Canadian gasoline and convenience store chain owned by multinational oil and gas company, Circle K. Here are some details about Ultramar:

• Ultramar was established in 1957 in Quebec, Canada, and has since then expanded across Eastern Canada, operating more than 400 gas stations and convenience stores.
