This is why TERB as it’s own Durham section to advertise in. The Durham guys look there. It would be advantageous for you to advertise here.
Posting in Durham, I never had a guy from the GTA think I’m in Toronto. I had a couple ask if I would tour Toronto but never assumed I worked there.
Just stick to this section, put Durham in your signature and in any ad outside of the Durham section and it will be fine.
Many outside of Toronto say that TERB is expensive. It is basically one hh call or less a month but the ROI is much higher making it worth it. They just haven’t tried to see what clients can get brought in.
