Over the Rainbow looks like a fantastic anthology, but be aware that it is open only to Canadian Citizens and residents. I've noticed a lot of Canadian markets have a requirement like this, which I believe ties into Arts funding constraints:
All writers must be Canadian citizens (living in Canada and/or paying taxes in Canada) and permanent residents of Canada
If you meet those criteria though, it looks good:
Fairy tales are often about the encounter with the strange, fantastic, and otherworldly. They are frequently used as texts of warning, inspiring conformity by telling people what they shouldn’t do. We want to explore the power of fairy tales as texts of resistance, as ways of speaking back to those power structures that try to get us to conform. Over the Rainbow will be an anthology that explores the power of fairy tales to introduce the under-represented. We encourage authors to explore Queer (LGBTIA2 and QUILTBAG) stories, tales of people with disabilities, tales of mental health, poly relationships, and bodily diversity. Our hope is to use fairy tales to smash tradition and reshape it with (dis)enchantment. Over the Rainbow seeks to bring readers into the woods where transformations and new beginnings can happen. We hope to play with traditional fairy tale tropes in unconventional ways, offering a shattered mirror image of our world and our imagination.
They're after all (speculative) genres on the theme, and paying 0.05 Canadian cents per Word for 2,000 and 5,000 Words, as well as a contributor copy. You have until August 31st to get your submission in!
