In my opinion, the seat belt chime should not come on until car reaches say 30kmph, sometime I just back the car out to the driveway so I can get stuff out and is beeping already.
For the US, FMVSS 208 requires the chime, and MPH KPH trigger is right out... Not sure what the Canadian requirement is.
