Different nationalities have different entry requirements. For this reason, it is advised that the very first step you take towards Canada travel is to check if you will need a visa to enter the country. This is a piece of information that you can find quite easily online, but just to double-check, you can always call the Canadian embassy/high commission. Due to the COVID-19-related backlog, visas may take longer than usual to be processed; therefore, get the process started as early as you possibly can! Any other paperwork, such as vaccine certifications, must also be in check by the time your departure date is close. While having soft copies on your phone is a great and functional way to go about things, a hard copy or two of very important certifications is not a bad idea. You never know when you'll run out of battery!
