跟你付费的时间没关系。

目前没有查到关于多久可以批准的直接描述，比较值得参考一下的官网原文是说，加拿大卫生部MF管理处将在收到完整材料包后30个日历日内处理（process）所有MF交易相关信息及材料（该日期视为MF行政程序完成日）。强烈建议MF持有人至少在申请人提交药品申请、DIN申请或CTA提前2个月完成MF或新LoA的注册。这里不确定“处理process”是否可以直接理解为批准。

希望对你有帮助。

Master File Performance Standards

Health Canada's MF Administration Unit will process all information and material filed with an MF transaction within 30 calendar days of receiving a complete package (the date the MF is considered administratively complete). MF holders are strongly encouraged to register MFs or new LoAs at least 2 months ahead of an applicant's drug submission, DIN application or CTA.
