Sainte-Adele is within an hour of driving time from Montreal, and approximately two and a half hours from Ottawa, the capital of Canada. The Workshop will be held at a time when the mountains will be clothed in splendid fall colors. Outdoor recreational activities, besides fall foliage viewing, include water sports on the lake, tennis, golf, hiking, mountain biking, and horseback riding. Indoor facilities available include fitness equipment, swimming and whirlpool, sauna, and courts for squash, racquetball, and badminton. WORKSHOP REGISTRATION Complete the Workshop registration form and return it to the Workshop Registrar by mail or fax. Authors who have already registered may use the Workshop registration form to sign up for the pre-arranged bus service. Your payment may be remitted by a cheque or money order in Canadian dollars, payable to 1993 IEEE Workshop on Speech Coding. You may pay by charging to a credit card (fax registrations must charge to credit cards); only VISA or MasterCard can be accepted. The registration fee covers Workshop attendance, social events, and one copy of the Workshop Proceedings. Additional copies of the Proceedings may be purchased at the registration desk for Cdn $40 each. Meals are covered separately by your accommodation arrangement with the Hotel (see below). Persons accompanying Workshop delegates and who are not attending the technical sessions of the Workshop need only register with the Hotel; however, accompanying persons are welcome to participate in the social functions organized for Workshop delegates. Registrations will be accepted on a first-come-first-served basis. Registrations received on or before September 15, 1993 are eligible to pay the advance registration fees, and registrations received after September 15, 1993 are required to pay the late registration fees. Any arrears due to a difference between your remittance and the applicable fees will have to be cleared when you check in at the registration desk. To prevent overcrowding, the Organizing Committee reserves the right to limit enrollment and will notify registrants of their registration status. On-site registration is treated as late registration. Due to limited enrollment, on-site registration will not be accepted without prior approval from the Workshop Registrar. The registration fees are refundable, minus a Cdn $30 cancellation charge, provided a written request is received by the Workshop Registrar by September 30, 1993. With written notice to the Registrar, a registration may be transferred to another person without charge. ACCOMMODATION Workshop delegates are responsible for making their own reservations for accommodation directly with the hotel. Complete the hotel registration form and return it to Hotel Le Chantecler by mail or fax. September 13, 1993 is the last date by which room availability is guaranteed for Workshop delegates. The hotel daily rates cover three meals (supper, breakfast, lunch) each day, but a tax of 11.28% will be added to the hotel bill. On the hotel reservation form, you may also sign up for the lunch served on October 13 prior to the commencement of the Workshop. Delegates are welcome to make reservations with Le Chantecler for earlier arrival or later departure. Alternatively, you may wish to stay in a hotel in Montreal before and/or after the Workshop. Greater Montreal with its 3 million population is renowned as the second largest French city in the world (after Paris). It has so many things to offer that no short description here would do justice! For touring information and suggestions, you may call Tourism Quebec at (800) 363-7777 toll-free from Canada and the U.S. or (514) 873-2015 from elsewhere.

Mirabel Airport is located in between Montreal and Sainte-Adele. Delegates may choose between driving to Le Chantecler themselves, taking a bus from downtown Montreal that has been pre-arranged by the Workshop Organizing Committee, and taking a taxi. Driving Instructions >From Montreal, Dorval, or Mirabel, it is necessary to get on Autoroute 15 (Autoroute des Laurentides) and head north (northwest geographically) to reach Sainte-Ad=E8le. If you are renting a car, ask your rental agency for directions and a map. Autoroute 15 skirts the eastern boundary of Mirabel Airport. From Mirabel to Sainte-Ad=E8le, take Autoroute 15 in the direction going away from Montreal. From Dorval Airport, head towards Mirabel Airport and continue on Autoroute 15 to Sainte-Ad=E8le. One possible route from Dorval is to take 520 east (northeast), then 13 north (northwest), then 640 east (northeast), and 15 north (northwest). While you on Autoroute 15 north to Sainte-Adele, take Exit 67 and follow Route 117 north. At the 4th traffic light, turn left on rue Morin. At the top of the hill, turn right on rue Chantecler and continue on to Hotel Le Chantecler. The Hotel is about 3 km from Exit 67. Car Rental Most multinational car rental companies also operate in Canada, usually under the same name. One notable exception is Tilden, which is affiliated with National in the U.S., Europcar in Europe, and Nippon Car Rental in Japan. To reserve a car, we suggest that you call your one of the car rental multinationals or a travel agent in your home country. Pre-arranged Bus Service To/From Sainte-Adele The Workshop Organizing Committee has arranged for bus service between downtown Montreal and Sainte-Ad=E8le, with optional stops at the two airports on the return trip. Registrants wishing to use the bus service should indicate so on the Workshop registration form. The fare is Cdn $20 one way, prepaid with the registration. Registrants who have prepaid the bus fare are guaranteed seats on the bus. Those who have not prepaid may board the bus if seats are available; no additional bus service will be enlisted for non-prepaid passengers. The bus fare for non-prepaid passengers is Cdn $25 one way, payable upon boarding to a Workshop official. The bus will leave from downtown Montreal for Sainte-Adele on October 13, at 11:00 a.m. Passengers will be picked up at the Mansfield Street entrance (near the intersection of Mansfield Street and Rene-Levesque Boulevard West) of the Queen Elizabeth Hotel. On October 15, the bus will leave Sainte-Adele for the Queen Elizabeth Hotel at 4 p.m. Passengers on the return trip wishing to disembark at Mirabel Airport or Dorval Airport should notify the driver before the bus departs Sainte-Adele. Bus Service Between the Airports and Montreal Autocar Connaisseur operates scheduled bus service between three locations: downtown Montreal, Dorval Airport, and Mirabel Airport. Boarding in downtown for the airports is at the Mansfield Street entrance (near the intersection of Mansfield and Rene Levesque) of the Queen Elizabeth Hotel. The Dorval-downtown service operates every 20 minutes during most hours of the day and every 30 minutes in the early morning and late night hours; the cost is Cdn $8.50 one way and $16 return. The Mirabel-downtown service operates hourly before 12:00 noon and every half hour after 12:00 noon; the cost is Cdn $13 one way and $20 return. The Dorval-Mirabel service operates hourly in the periods 9:20-11:20 and 20:20-23:20, and every half hour in the period 11:20-20:20. Delegates planning a tight itinerary are strongly advised to call Autocar Connaisseur at (514) 934-1222 for the exact bus schedule. Taxi Taxi service between Dorval and downtown Montreal is currently fixed by regulations at Cdn $24. The taxi fare is roughly Cdn $60 between Mirabel and downtown. Between Mirabel and Sainte-Adele, the taxi fare is approximately Cdn $40. You may choose to take a bus from Dorval or downtown to Mirabel (see bus information above) and then take a taxi to Sainte-Adele. Required Documentation It is the responsibility of the delegate to comply with all Canadian border entry requirements. Please ask your local travel agent or nearest Canadian Embassy or Consulate what travel documents you need to visit Canada. You might also need to check with your local authorities concerning documents required for returning to your country of residence. Health Insurance Visitors to Canada should have adequate medical insurance coverage! Canadian government health plans do not cover non-residents visiting Canada. We strongly suggest that you obtain health insurance that covers you during your stay in Canada. Currency There are banks and money changers in the airports and downtown Montreal. However, we suggest that you carry some Canadian money with you prior to arrival in Canada. American dollars are accepted for many transactions, though an exchange rate premium may be incurred. As for delegates holding a currency not widely circulated internationally, it would be prudent to obtain Canadian or U.S. dollars prior to departure for Canada.
