You would have to bypass the on/off part of the light switch, but not the high/low beam part. That would be trickiest. A relay for the lights tied to any ignition-switched power source would get them to come on when you start the engine and shut off when you stop it.

That's not very helpful without specific details, I realize, but that would be the strategy. Try googling "daytime running light conversion canada" and see what comes up...

Good luck!
