If you are interested in hotel and flight packages, you can compare what's available on TripCentral. http://www.tripcentral.ca/

It pulls together several different tour company information and you can search by destination and departure date. Use the Vacation Search and choose Turks & Caicos. You can even fine-tune your search on the results page for meal plan or no meals. For Turks & Caicos, Air Canada Vacations, Conquest, Signature, Club Med all offer trips to this destination.

You may be able to get the vacations cheaper elsewhere - I haven't checked - but this is handy for Canadian travelers.
