There are a lot of options on the internet you can google it for sure. Some of my friends recommend this one:
https://www.justforcanada.com/order-gcms-notes.html - They will analyze and make suggestion for you as well. For me, I just use:
https://caipsnotes.com - Typical GCMS note but the service will not give any analysis or suggestion for you. If you know someone present in Canada, you can ask that person to use ATIP Online Request through this:
https://atip-aiprp.apps.gc.ca/atip/welcome.do?lang=en - It just takes 5$ per request and your consent form attached with. I know some people use "clone" email, address, and information to request ATIP online for only themselves, but I do not want to risk this.
