Canada House is in Trafalgar Square in Central London and, although it is closed to the public at the moment, their most recent gallery show is online.
Meryl McMaster's As Immense as the Sky uses her Canadian heritage ("Nêhiyaw (Plains Cree) and a member of the Siksika First Nation on her father’s side and has British, Dutch and Scottish ancestry on her mother’s side.") to explore her own identity alongside her relationship to the natural world in huge photographs of costume, staging and performance. Aren't they fantastic?!
There is more information and a short film here too of Meryl's work, and an audioplayer, at the bottom of the page, that accompanies the exhibition, by Jeremy Dutcher.
