Questions
What is the closest city to Ontario?
Rancho Cucamonga is the nearest city or town of 15,000 people or more, 4.5 miles (7.2 km) northeast of Ontario's centre in a straight line. A smaller town or a suburb may be closer.
Are these driving distances from Ontario?
No. Every distance on this page is a straight line between two centre points, as the crow flies. A road route is always longer, because roads bend around terrain and water, and MapGO does not measure driving distance or travel time.
Which places count as near Ontario?
Every city and town of 15,000 people or more in the GeoNames gazetteer whose centre lies within 200 miles of Ontario's centre. Villages and smaller towns are left out, so there are more places nearby than listed. A place right on a ring may fall either side of it, depending on where its centre point sits.
Places and their centre points from GeoNames (cities and towns of 15,000 people or more); distances computed by MapGO with the haversine formula. All distances on this page are straight lines over the Earth's surface, not road distances.
