Hey gang, new guy here. love the forum

Sorry to drop another tax question but I did read through all threads here first regarding taxes and although they were very helpful I'm still a little confused on what taxes exactly a mom owner should be paying? From what I gather it looks as though one should be at least paying GST(if this incorrect someone please let know) but should they be paying something else as well? Or Is just paying GST sufficient? And does it make difference if located in SK?

Thx for your help guys.
