Canadian Stocks?

Hello today,
I love your site and plan on registering soon actually, but i did have a couple questions:

1) Would it be possible, and/or do you have plans on adding the Canadian Companies of the TSX (Toronto Stock Exchange). I don't know the technicalities (that does not look spelt correctly LOL) of whether that would be a huge undertaking, or whether the process is mostly automated (ie, i wouldn't suspect the US stocks have their values entered manually, continually).

Hmmm, come to think of it, if i were to click on a stock on the home page, it tells me:
"Analyzed by Serenity on Friday, July 10, 2015 - 00:30"
Does this mean you've manually entered all those values? No. Please tell me you've outsmarted me and have created a program to frequently update them?

2) Just a quick question, Im looking for a really basic definition of Defensive, enterprising and NCAV...
Let me know if i have this correct: Defensive stocks are the most strict, and least likely to come across?
Enterprising stocks are less strict in their criteria, but have more potential for growth/ gains?
NCAV: Should be "impossible" to lose everything?

Do you have any sort of post by chance that would sorta outline what each one really means, when, by whom, and with what goals in mind?

I apologize in advance for asking such basic questions, im still early on learning and have had more concussions than sometimes allows me to recall simple things.

Thank you so much for your help.
