Saturday 18 June, 12 noon outside the Canadian High Commission, Grosvenor Square, London:

On 18 June the biggest ever international demonstration against the Tar Sands will take place, with people holding events outside Canadian Embassies around the world.

Join us in London and help:

• raise awareness of the world's most destructive project
• let Canada know that the whole world considers tar sands a step too far in dirty development
• demand a moratorium on further exploitation of tar sands

Listen to powerful speakers and entertaining music; join us in a massive game of Oily World Volleyball; and bring flowers and messages to deliver our sombre feelings to the Commission.

This is a defining moment in our history, a time to make a choice, to draw a line in the sand and say this is too far, too much is at stake and we have to make it our choice.
