a little internet searching found the following;
Here is one association in the states
http://www.acra-crm.org/ There is likely to be one in BC.
Also this link is to laws pertaining to preservation , thus would lead me to belive there has to be a agency that enforces, provides assistance, etc.
http://www.qp.gov.bc.ca/statreg/stat/H/96187_01.htm And one final but most promising link,
http://www.mcaws.gov.bc.ca/heritage_branch/index.htm Best of luck
