Migrant Farmers Who Are Recruited to Plant and Harvest Fruit

Migrant farmers who are recruited to plant and harvest fruit and vegetables, primarily in Southern Ontario work under exploitative and substandard conditions. However, many of them return year after year because

A) They signed 10-year legal contracts with Canadian farmers and if the individual who signed the contract does not return, they must send a family member to do the work
B) Individuals earn valuable Canadian currency which is used to support their families back home
C) Many of them have married Canadian women and have actually moved into houses that are situated on the farm itself
D) They are one day hoping to run away from the farms with their family and apply for Canadian citizenship as refugees
E) They don't know they are being exploited
