Dawn Johnson is employed by Alberta Oil Ltd. as an oil well technician in Edmonton. She has accepted a transfer to the Egyptian offices of the company for three years beginning January 1, 2020. Dawn severs her residential ties to Canada on December 31, 2019, and takes up residence in Egypt. Alberta Oil continues to pay her salary. Although the government of Egypt would normally tax such salary, the tax treaty between Canada and Egypt exempts the salary from tax in Egypt. Is Dawn required to pay Canadian tax on the salary paid to her by Alberta Oil? Justify your conclusion.
