Note: To enter Canada, you must provide proof of citizenship. Accepted forms of ID include a birth certificate and photo ID or a valid passport.

Toronto is Canada’s largest and most diverse city, home to over 100 cultures. The Westin Harbour Castle Hotel lies in the very heart of Toronto, on the shores of Lake Ontario. The Westin Harbour Castle allows guests to relax in luxury and comfort, offering a wide selection of on-site dining and friendly service.

The hotel is located just minutes from Toronto’s business center and is only a short walk from major attractions such as the Air Canada Centre, the SkyDome, and the CN Tower, as well as the Theatre District. Dining options include 24 hour room service, a Lobby Lounge, the Mizzen Restaurant, Toula Toronto and the Chartroom Restaurant. An indoor pool, a fitness facility and a whirlpool/hot tub are also provided for Westin Harbour Castle guests.

Identification and Currency Exchange

Citizens and legal residents of the U.S. do not need passports, but they are preferred. Native-born U.S. citizens should have a birth or voter’s certificate showing citizenship and photo identification. Naturalized citizens need a naturalization certificate or other evidence of citizenship. Permanent residents (non-U.S. citizens) need their alien registration cards.

Attendees coming from countries other than the United States may require a visa to enter Canada. When making your travel plans, be sure to consult with the Canadian Consulate or Embassy in your country to determine whether a visa is required.

Every 30 days, returning US residents are allowed to take back $400 (retail value) worth of duty free merchandise provided they have been out of the US for 48 hours.

US funds can be changed into Canadian funds at any bank or exchange house; some identification may be required. Most places accept American currency, but banks and exchange houses give the best exchange rate. Other foreign currency needs to be changed at "special exchange house" located at the airport and train station. Ask your hotel concierge for other locations. Credit cards are accepted almost everywhere.

Goods and Services Tax

The goods and services tax (GST) is a 7% tax that is charged on most goods and services sold or provided in Canada. Foreign visitors to Canada can apply for a rebate on the GST paid on accommodations (up to 30 nights per visit) and on goods purchased in Canada and subsequently exported within 60 days of purchase. We will supply all registered meeting attendees with information regarding the "Tax Refund For Visitors" program.

Shipment of Workshop Material

The service of a customs brokerage firm is strongly recommended for all shipments originating outside of Canada. This will eliminate the possibility of materials being held at the border by Canada Customs due to improper or insufficient documentation resulting in these same materials arriving too late or not at all to the hotel. Mendelssohn has been appointed as "official customs broker." Please contact the Toronto Mendelssohn office directly at the following phone numbers to assist you with your customs needs.

Do not ask SIAM. Please go directly to our Canadian contact.
