Watch: first trailer for Ellen Page-helmed documentary 'There's Something in the Water' unveiled

Nova Scotia native Ellen Page returns home in order to investigate something that may topple the notion that "Canada takes care of its people". Canada isn't only a magical land of opportunity for Irish youth on working holiday visas – it also has a harrowing and ongoing history of colonisation that is rarely so openly addressed. There's Something in the Water explores the devastating effects of environmental racism on indigenous and black communities in Nova Scotia, Canada.

In the trailer, Ingrid Waldron (who serves as both producer and author of the book on which the documentary is based), can be heard saying: "In Canada, your postal code determines your health. So we know that where you live has bearing on your wellbeing. Indigenous and black communities are the ones that tend to be located near hazardous sites."

The Umbrella Academy star premiered the film at the Toronto International Film Festival in 2019. Page is the first to admit that she's privileged, but she is using that privilege to try to affect real change for marginalised communities, who have "been fighting for decades" to secure their own wellbeing. Watch the chilling trailer below.
