DRL are federally mandated, not provincially. Auto manufacturers had to implement them to meet federal safety requirements, along with third (or high mount) brake lights.Generally the people that disable them think their car looks better without them on. They simply refuse to believe they make any difference. Oddly enough they do seem to agree with bikes needing headlights on all the time. Bikes made for USA and Canada do not even have provisions for turning the headlight off.
