Though the legal aspects relate specifically to Ontario, the materials are very useful.
Here they are: Legal Backgrounder on Trans Parents and Family Law in Ontario(great to give to your lawyer if you are trans and have a family law issue); Transgender Parents and Ontario Family Law: Parenting through Transition, Together or Apart.
Rachel is doing a weekend workshop for trans people interested in parenting, in Richmond on February 21-22, sponsored by BC Council for Families. I'll be doing the BC legal part. Cost of the workshop is $175. If you are interested, go to the BC Council of Families website: www.bccf.ca
