LUSH has an events calendar on its website. Lots of stuff always happening around the country. Some have free giveaways, some don't.

Too much to list on my blog, so check out http://www.lush.ca/shop/events/. Cities with events include Victoria, Vancouver, Calgary, Whistler, Prince George, Ottawa, Banff, Markham, Montreal, Newmarket, Ste-Catherine, Guelph, and Kingston.
