Update (Jan 2009): We have networked with community and business groups around Hamilton to establish what is now the Hamilton Vegetarian Society. Our local section is dedicated to the increasing need to become locally self-sustainable. Our events section offers you all the activities we organize to bring the vegetarian community together.

London Ontario Vegetarians for the Environment (LOVE)
Purpose: To foster respect and compassion for all living things. To bring to the forefront, the escalating environmental devastation to our planet caused by factory farming. To inspire each individual to take action to make the world a better place for people, animals and our environment.
