租車問題 - 加拿大

八月初要在calgary機場租車遊玩banff
因此選擇hertz租了一禮拜的車
車款Standard, SCAR Dodge Avenger
依照網頁最後價錢顯示 343CAD包含了

Concession fee recovery Included
Loss Damage Waiver Included
Super CDW: Included
Taxes Included
Vehicle Licensing Fee Recovery
& Air Cond Surcharge Recovery Included
Customer Facility Charge: Included
ENERGY SURCHARGE Included

好像只缺少Liability Insurance Supplement可以讓我加選
第一次在加拿大租車,想請問有經驗的朋友
這樣的價格及內容算OK嗎?
查過其他租車網要含這些險都要500CAD以上
不知道hertz有沒有問題,到現場還要加一些有的沒有的
感謝各位解答
