The North Shore is a region of Quebec on the north shore (obviously) of the Gulf of St. Lawrence.
The region of Quebec east of the Natashquan River uses Atlantic time zone of UTC -4 and does not use Daylight Saving Time. So clocks in the extreme far east of Quebec match Labrador City in the winter and Montreal in the summer.
As this region of Quebec is near the Atlantic Ocean, many storm systems can be very intense throughout the year with a lot of snow throughout the long winter. Temperatures can very significantly throughout the day and year.
