请教CPP/EI Exemption是什么意思

angel0211

大家好，我才到加拿大上班，税务方面一头雾水。

- Y- X$ H0 x6 C! V' C. Q: l7 J6 a" A& R入职时小蜜给我一份CPT1表格填写。"Aplication to Canada Revenue Agency for CPP/EI Exemption". 请问这个表格是申请什么的？是申请不缴CPP/EI吗, 还是其他意思？
2 x" X/ |/ W; v7 [; d9 c) Y
4 k2 {" ]: E% x1 E; n* s/ Z表格里有这么一段话: ”XXX must make CPP and EI deductions from workers. However, if you interpret your income to be CPP/EI exempt, you must apply to CRA directly for a ruling on whether your employment is pensionable and/or insurable, or both”
6 v7 c, O/ B3 O6 p, m& N: E“ruling”是什么意思啊？

谢谢各位啦！
