If you feel like Montreal has been perpetually digging out from more than our usual share of snow dumps this year, you're not wrong. On Thursday, the city launched its seventh snow clearing operation of the season to clean up the mess left behind from storm earlier this week. By Friday morning, 23 per cent of the city had been cleared. Typically, the city sees about five snow events that require the full clearing efforts a year. Already, 235 centimetres of snow has fallen since the start of winter.
