As of today, all Americans and Canadians entering the US at land and sea entry points will be required to present a passport or a driver's license accompanied by a birth certificate from Canada or the US, a naturalization certificate or other proof of US or Canadian citizenship. The Discover America Partnership is pointing out that the Canadian government is running an extensive public service television advertising campaign to educated Canadians on the new requirements (which are the same for people entering Canada). They're urging support for the Travel Promotion Act which would fund a campaign to promote tourism to the US and educate visitors on how to avoid problems entering the country.
