Totally agree with Josh. You cannot legally rely on any inferred data, as it's known to be unreliable. "I didn't know you were in Canada" is not an excuse.
Yes, I agree the inferred location cannot be relied upon. It is set only once (never updated after the first visit) and is often inaccurate (due to VPNs and whatnot). When I reached out to Marketo support they recommended not using it to determine location of individuals, but rather get a ballpark snapshot of where visitors as a whole are coming from.
