I would like statistics of hog farming in Canada (such as the total
number of hogs, how many hogs per farm, how many farms there are,
economic contributions from hog farming, exports, etc.) as well as
information on trends taking place in the industry.

Some Ontario info:

Hi, N-P...

I expect that you would find all the information you can comfortably
absorb from the site of the Canadian Pork Council...

http://www.cpc-ccp.com/

...and from Industry Canada's "Strategis" website.

http://strategis.ic.gc.ca/engdoc/main.html

A thorough exploration of those sites will give you as in-depth an
insight into the industry as you might wish.  You probably will find
that your own province also has a pork marketing board, which should
be a good resource for you as well.

Digging through these sites, and extracting information on your
behalf, would unfortunately require far more time and effort than the
$2 price tag warrants.  If you would like for one of us to provide you
with something of a summary, you may wish to post a new question, or
alternately raise the price of the current question.

Regards,

You are asking for several pieces of specific information here that
would take some time to formulate. I recommend increasing your
Question's price according to Google Answers pricing guidlines in
order to receive the best possible service and prompt attention.
