I know that in Ottawa, while they have similar "snow route" procedures, the generally accepted rule is that you park on the street at your own peril. If there's a snowfall that night, and the plows come by while your car is parked there, it's fully within their right to bury your car under a mountain of snow. Don't like it? Don't park on the street. Or at least pay attention to the weather forecasts.
I've seen it a few times in my neighbourhood where someone parked on the street, and the plow went by and buried their car to the point where they had to shovel it out of the side of the snowbank which had swallowed their vehicle.
