Two Canadian and two Mexican photographers have been shortlisted for the second annual Grange Prize, a $50,000 award given by the Art Gallery of Ontario.

Lynne Cohen of Montreal and Jin-me Yoon of Vancouver are the Canadian finalists, alongside international candidates Marco Antonio Cruz and Federico Gama, both of Mexico City.

The Grange Prize is a partnership between the AGO and Aeroplan that recognizes both Canadian and international photography - and bears the distinction of being the only Canadian photography prize whose winner is selected through a public vote.

Each year, a curatorial panel selects the finalists from Canada and one other country - Mexico earned this year's honour - but the public votes for the winner through the prize's website.

And for the first time, special exhibitions featuring the finalists' works will be held in both countries. The AGO will mount its show April 21 to June 26; Mexico City's Centro de la Imagen hosts a concurrent exhibition from April 8 to May 24. (The AGO is also planning a solo exhibition featuring last year's winner, Winnipeg's Sarah Anne Johnson.)

The Grange also gives all four finalists foreign residencies. The AGO will house Cruz and Gama, while Cohen and Yoon will travel to Mexico. Themes during the residencies include Canada's First Nations and Mexican immigration to Canada.

Grange Prize voting closes May 20, with the winner announced May 26.
