Calgary's immigration formalities should go to the United States at the border, right?

It will be faster if we go to the US-Canada border. Otherwise, you can make an appointment at the CIC office in Ka Cheng.

I handled it at the border. Take the immigration confirmation and passport of permanent residence, and if you have other supporting documents, you might as well take more. Then follow Highway 2 to carway Border Guard Station. When you enter the United States, say that you have come to apply for immigration to Canada. They will stop you, go to the office and give you a piece of paper refusing to enter the United States. With this paper, when you drive back to Canada and enter the Canadian border, you will be asked to stop and enter the office. Waiting for your name to be called. There was basically no queue when I went, and it was finished in about half an hour.

Good luck.
