After receiving the COPR, you have to check all the information on your COPR, if there is any MINOR errors observed (data of first and last entry, place of birth), you should note down and let the officer at the border know when you go there for landing. Bring your passport, 2 papers of COPR, proof of fund and head to Niagara Falls-Queenston-Lewiston Bridge for landing. First you should do Flagpole: When you arrive to the bridge, come to see the officer at the border gate and let them know that you have COPR and want to do landing. They will ask you to go to the US side to do flagpole. When you head the US side, let the US officer know that you want to do flagpole for Canada PR and they will help you to do that. The border office only work on Tuesday, Wednesday and Thursday from 8.30am to 24.00pm. You should go there in the early morning so that there are not too many people at the border. The people at US side are nice but they are strict, do what they ask so that no problem will be occurred. When you back from US side, the border office will instruct you what you should do next. Just wait patiently and you will get it done in about 1 to 2h, depends on if there are many people there. Good luck with your landing.
