Holding two permenent residencies simultaneously?

Question

This question is for immigration lawyers who reside in both the United States and in Canada.

My family just received their permanent residency status in the United States within the last year (green card). We are living in the United States. While this processing had been going on, our Canadian immigration process had also been going on as my sister is a Canadian resident and she had urged us to start the processing. Well, just yesterday our Canadian immigration application was also approved and we were asked to come to Canada for landing purposes.

So my question is, can you only have one permanent residency at any given time, or can you maintain both the US and the Canadian residencies at once? Also, if you could refer me to any good Canadian immigration lawyers who can answer my questions on this, I would really appreciate it!

If going for landing in Canada means giving up my US permanent residency, I do not want to go with that. I also don't want to do anything illegal.

Answer 1

If you RESIDE in a country permanently then that means that you live there in excess of 6 months per year.  This is not possible to do in two countries as there are only 12 months in one year.

Answer 2

You can only be a permanent residence in one of the two countries.  You need to decide as soon as possible, and notify the state department of each country of your choice.
