I am a Canadian PR and currently work in the US. I will be relocating to Canada in January 2019. I work with a particular company in the US and will be internally transferring to their Canadian office. My base location will be Canada but I might have to travel on Monday mornings to the US office for the project and will return to Canada on Thursday nights for a couple of months. What will be counted as the physically present days in Canada for the purpose of maintaining my PR status?
