The lack of hours is precisely why. The workers don't work enough hours to cover the entire season and can't qualify for employment insurance, or EI. When they try out a seasonal job, they can't stay in it because they can't make it through the winter. They are forced to find other jobs. Usually, it is people who move to the region and leave after one or two seasons, because they realize that they can't survive all winter.
