Toronto is located in the southern part of Ontario which puts it beyond the aurora oval where the stunning natural phenomenon can be seen the best. However, you will still have a good chance to catch a glimpse of dancing lights in just a few hours from the city. The phenomenon of Northern Lights is caused by geomagnetical activity or disturbances which are measured in Kp-Index on a scale from 0 to 9. The Kp-Index has to be at least 4 for a successful aurora hunt in the Toronto area. You have almost no chances to see it in the big city because of light pollution. You have to get away from Toronto and try your luck on the shores of Lake Ontario. Or drive a bit further to visit one of the designated dark sky areas nearby.
