Siren was a bimonthly Canadian magazine, published in Toronto, Ontario for the city's lesbian community. The magazine was launched in 1995 by a women's collective of volunteers. Its popularity increased in late 1996, around the time the lesbian monthly magazine Quota ceased publication. It underwent a controversial editorial revamp in 2002, ending its association with its regular contributors in favour of a more freelance story and contribution structure. The magazine was quoted in a discussion paper released by the Ontario Human Rights Commission about extending rights for transsexuals. One of the columns that appeared regularly in the magazine was titled "Dykes n' tykes".
