Your question is a bit hard to answer in the abstract. If the name is an original one, and the other party is in Canada, there is probably very little risk unless you are in a "related-industry" scenario. Much will depend if the Canadian firm is doing business in the US. You could try to obtain the consent, but if they don't know about your existance it might be like waking a sleeping dog.
