This is our tribute to all those in the past who were never allowed to marry by law – and to everyone who is still denied the right today. Share your love stories, wedding photos and videos on Instagram and Twitter with #lovemadelegal and let’s make gay marriage legal everywhere.
Thank you PFLAG Canada for this wonderful video:
