From the U.S.Embassy website;
Canadian citizens do not require a visa to enter the United States directly from Canada for the purposes of visiting or studying.(F-1, 1-20?)
Intending immigrants, fiances or investors must qualify for a visa before entry in the same manner as other nationalities. Other entrants, such as journalists, temporary workers or NAFTA professionals must present all necessary supporting documentation and/or approved petitions directly to a U.S. Customs and Border Protection (www.cbp.gov) Officer at the Port of Entry.
Canadian visitors present proof of citizenship (Passport / Birth Certificate / Naturalization) and a government issued photo ID (Passport / Driver's License / Provincial Health Card) at the U.S. Port of Entry. A valid Canadian passport is required when arriving in the U.S. by air, or from outside of the Western Hemisphere, and will be required for all air, land and sea entries no later that June, 2009. Unlike some other nationalities, as a Canadian, your passport need not be valid beyond the duration of your planned trip to the U.S. and it need not be machine-readable.
Please be sure to check the U.S. Customs and Border Protection web site for the latest updates on U.S. entry requirements for Canadians and others.
Canadian visitors are generally granted a stay in the U.S. for up to six months at the time of entry. Requests by any foreigner to extend or adjust a stay must be made prior to expiry to the U.S. Citizenship and Immigration Service. All Canadians are reminded that U.S. law requires all foreigners to qualify for the desired stay and purpose at the time of their intial entry. A visitor who intends to live, work or study in the U.S. may be permanently barred from the U.S.

The Visa Waiver Program (VWP) enables nationals of certain countries to travel to the United States for tourism or business for stays of 90 days or less without obtaining a visa. The program was established in 1986 with the objective of eliminating unnecessary barriers to travel, stimulating the tourism industry, and permitting the Department of State to focus consular resources in other areas. VWP eligible travelers may apply for a visa, if they prefer to do so. Not all countries participate in the VWP, and not all travelers from VWP countries are eligible to use the program. VWP travelers are screened prior to admission into the United States, and they are enrolled in the Department of Homeland Security’s US-VISIT program.
Which countries participate in the Visa Waiver Program (VWP)?
Currently, 27 countries participate in the Visa Waiver Program, as shown below:
