Canyon will be rebranded as part of WRG following the acquisition, which was signed off yesterday (14 August).
Staff at both agencies were informed of the acquisition yesterday, and members of WRG are now working with Canyon on two projects for P&G and Jaguar Land Rover, to be held in September/October.
Board of directors
The acquisition – for an undisclosed sum – comes after private equity firm LDC invested £12m in WRG last year, to support a UK and international growth strategy.
Canyon managing director Jonathan Boyne will take a place on the executive board of directors at WRG, alongside chief executive Barry Day, and directors Carl Halliday, Mark Wallace, Chris Gosling and Nigel Bale.
Day said: "We have a shared commitment to creativity and an enviable record of successful delivery.
"The strength of our combined talents gives us enormous power to further expand both our suite of services and our geographical reach over the next 12 months."
WRG is headquartered in Manchester, where it has a 90-strong team, but has offices in London, Wycombe, New York, Abu Dhabi and Doha, Qatar.
Plans are underway to open an office in Hong Kong, which will be spearheaded by technical director Cliff Zenker and lead to the formation of satellite teams in Shanghai and Beijing.
Formed in 2006, Canyon has around 20 staff and works with brands including P&G, Clarks International, DFS, ABF, Nationwide Building Society and Jaguar Land Rover.
WRG was created in 2007 through the merger of With and Reflex Communications and employs more than 140 people across its five locations.
The agency managed the G20 London Summit in 2009 and the Papal Visit to the UK in 2010.
Canyon’s Boyne said: "This is an exciting opportunity both for our combined teams and clients. We’re looking forward to being part of WRG’s future growth story."
