[GNC] Canadian Sales Tax Questions and/or "Canadian Version" of GnuCash

[Patrick Farrell]

Is there a "Canadian Version" of GnuCash as all the documentation in the 
current version of GnuCash 3.4+ (Build 2018-12-30) that I have read 
relates to the USA Tax System?

I immediately need to know how to set up automatically calculating how 
to add Canadian Harmonized Sales Tax ("HST") @ 13% to any Invoices I 
make up and send out to Clients/Customers, and then how to separately 
account for HST that I pay on any invoices that I receive from our 
vendors and subsequently pay. I then need to offset the HST received 
from Client/Customers versus the HST I have paid out to Vendors and do 
an official Government HST filing at least Quarterly, and pay them the 
difference if any!

Is there an "Update" software function in the program somewhere, as I 
have not been able to see any obvious place to do this? I see there is 
GnuCash 3.9 version offered on the website, but will I lose all existing 
data in my existing GnuCash 3.4+ if I download 3.9 on top of it or have 
to delete 3.4+ before I install version 3.9?

Any suggestions would be helpful.
