Many reputable tour companies offer singles-only trips, and some of them dip into the Maritimes. Singles Travel International (tel. 877/765-6874; www.singlestravelintl.com) offers singles-only escorted tours to faraway places like London, Alaska, Fiji, and the Greek Islands; in past years, its fall foliage cruise has touched down in Halifax.

The popular outfitter Backroads (tel. 800/462-2848; www.backroads.com) offers active-travel trips to destinations worldwide, including several hiking, cycling, and kayak tours in Nova Scotia and a fun bike tour of Prince Edward Island.

Remember that on some package vacations to Canada, as a single traveler you might be hit with the dreaded "single supplement" to the base price. To avoid it, agree to room with other single travelers or find a compatible roommate before you go from a specialized roommate-locator agency.
