Running Routes around Ajax

Hello everyone! My husband and I moved into Ajax about a month ago. The moving process really killed our fitness routine and we're trying to get back into the swing of things. We typically will run 5K every few days. Normally we'd map out our own 5K route on Google Maps and that usually ends up being fine, but because we're not familiar with the area we're not sure if there are better places to run through than others when it comes to traffic lights or streets that just aren't generally great to run down even though they may look fine on a map.

Does anyone have a 5K route they use that we could look at to try to build our own or any suggested places to focus on running around/avoid running around?

Edit: Sorry, didn't think to include my area. Ideally around Westney Heights would be good, but we're open to driving to our "start line" as well so honestly anywhere works.
