But is it to your MAC address or not? 
 
So my guess now is probably some nitwit has a DHCP server working the
Shaw network side rather than their internal side?  Or maybe a
deliberate hack attempt to hand out bogus IPs?

The router is probably not the DHCP server, it's just the forwarder for a backend management system. My guess is that our AsustekC friend is making a request with a strange option 81 that's being blindly copied in the response and since DHCP is a broadcast at this point, you're seeing it.
