Generally, no, a standard Uber driver cannot take you directly across the international border between Niagara Falls, New York (USA) and Niagara Falls, Ontario (Canada). Most Uber drivers do not have the specific commercial insurance, licensing, or personal documentation required to operate a ride-hailing vehicle in a different country. If you request an Uber to cross the border, the driver will almost always drop you off at the foot of the Rainbow Bridge. From there, the most common and efficient method is to walk across the bridge (which takes about 10-15 minutes and costs a small pedestrian toll). After clearing customs and immigration on the other side, you can simply open the Uber app again and request a new ride with a driver licensed in that country. There are private car services and specific cross-border shuttles that are licensed for this transit, but for a standard app-based Uber or Lyft, the process is a "drop-off and re-request" at the border crossing point.
