Southern Ontario has some really nice terrain. What you need to do first is look at Google Maps (Satellite) or some other satellite imagery of the property that you are going to hunt. Key features you want to look for are: Wooded areas, low features, and water features. You need a mix of open and wooded terrain to successfully draw coyotes in. I usually set up along a treeline/hill feature with my back masked by trees or the hill. I set myself up looking along a treeline that is lower then ground around it, many coyote callers are concerned that a coyote will see you coming in but if properly anticipate where the coyote will come from and where you position yourself, it doesn't matter what you wear, the last coyote I took I was wearing blue jeans and a green stealth jacket (it is a goretex windbreaker that is actually a bit shiney). Coyotes travel in low ground and along natural lines of drift (basically think about how you walk through off road terrain - you are naturally looking for the easiest way to get to where you are going. Practice your calling - knight and hale calls aren't the greatest but they do work. Don't blow on the call like a whistle, what you want to do is make it sound like the animal your imitating (assuming you are using a mouse/rodent/rabbit call) sounds like it is crying and being tortured to death - so lots of short blows, modulate how much air you put through it, you can even use your hand over the opening to make it sound like the noise is being cut off by another animal. Call for about 1-2 mins vigourously and loudly, STOP, wait about 5 mins - watching the likely access routes to your "bait", call again 1-2 mins, wait about 5 mins. I do this routine for about 20-30 mins - don't give up too quickly! My first mistake when I got into this was quickly abandoning the routine because I didn't think anything was coming in. Coyotes have great hearing and if they are within 5 km of the stand they will hear it and it will take them some time to come in. When they get closer they will sometimes watch from a distance, so don't be disheartened if you don't see anything right away. Hope this helps. Hunting at night is fine if you have a good light source - coyotes seem to be less cautious at night but I prefer hunting at dusk and dawn (more dawn) as you can draw in the coyotes that were unsuccessful hunting more easily - hunger is the best motivator.
