Very low throughput with QCA9880

yes you're right. your country is vht80 blocked according to your 
regulatory setting. so it might be that ubuntu has just a outdated 
regulatory database
because the official regdb supports vht80 for canada

http://packages.ubuntu.com/source/precise/wireless-regdb


this is the package. what we see is just shit. ubuntu uses a regdb from 
2011 where vht support wasnt included. i know why i hate ubuntu. its 
designed for home entertainment but not for users

you can install your own version from the official git 
https://git.kernel.org/cgit/linux/kernel/git/sforshee/wireless-regdb.git/
