How to reach Ottawa government employees with local business discount?

Local jeweller here, we specialize in custom engagement rings and wedding bands manufactured right here in Ottawa. We're offering 10% off for government employees but honestly not sure the best way to get the word out. Any suggestions on reaching Ottawa's public service community?

We've looked at Union Savings but that's way too broad - we want to focus specifically on Ottawa government workers. We'll be announcing it on our website and social media, but looking for other ideas on the right channels without being spammy.
