How far it is from Toronto to Mexico by car?

It is not feasible to travel from Toronto to Mexico by car.

The distance between Toronto and Mexico would be approximately 3,800 - 4,200 miles (depending on the route taken) and would require driving through several countries, including Canada, the United States and Mexico.

While you can drive all the way to the US-Mexico border, from Toronto you cannot cross into Mexico due to the presence of a natural barrier between the US and Mexico known as the Rio Grande River (or Rio Bravo in Mexico), which would require a boat or other watercraft to cross.
