How to expand shipping options to Canada and globally?

[Ctmph2022]

Hello! I have a shopify store, and I only have shipping set up for the united States. I'd like to expand out to Canada, and I am even open to the rest of the globe. I use the Dsers Aliexpress and CJ dropshipping suppliers to set it up with. I'm trying to set this up the correct way so if someone can help me I'd appreciate it greatly. Thank you
