A slight aside, IT stands for Idiot in Training.....

CG stands for Computer Geek.....

...and Friday is their parade day....

Finally, even if Al Gore said he invented the internet, it is the telephone industry that invented the circuitry to even have it thought of. Artificial insemination at it's worst.

"B" is the best...bet ch'ya!

You can find as many opinions on this as there are people willing to ofer them. We know the origins of 568B. My opinion is that A was implemented in the days when combo data/voice wiring was punched down on 66 cross connect blocks in order to maintain the pair 1/pair 2 order on the block. Since everything is now on patch panels it makes no difference. Pick a standard and stick to it. B is most common in this country.

Not every one uses patch panels! I prefer using bix based network design, this method is more cost effective and gives you a plethora of configeration options. Patch panels usually become a shoddy mesh after being worked on by IT programmers. When I do work on patch panels I make my own patch cords and cut them to the perfect lenght this is more aesthetically pleasing then having 75 patch cords that are 5 feet too long. :rolleyes:

Most people in Canada use T568A but not all. "eh"

I think you answered the question of why 568A is popular in Canada. If you use other than patch panels A makes sense.
