Google Transit offers global transit planning, with very thorough coverage of the U.S. and Canada— in fact, most of the participating agencies use Google in lieu of an independent service. It is accessible in Google Maps.
Canada
HopStop similarly provides trip planning for nearly all major and many minor cities in the U.S. and Canada, and offers iOS, Android, and Windows Phone apps.

###Local
Most local and regional transit planners are provided by the operating agencies, and may not reflect all options. For example, commuter rail and rapid transit are often administered separately, and a trip planner for one service will often exclude other options.
