They're almost never (maybe never) allowed in the left hand lane on 6-lane stretches of highways like the 400-series highways.
I assume they're allowed in the left hand lane on 6-lane city roads. They may generally avoid it though because I assume changing lanes to the right is harder than changing lanes to the left. And so unless you're turning left up ahead, you'd want to stay in the centre or right lane.
