Picture ID challenge: T16's near Caen

[Hanno Spoelstra]

Here's a picture for Mark, Clive, or anyone else who fancies a challenge. This comes from the 1970 vintage Marshall Cavendish Encyclopedia of WWII and is credited to IWM, who cannot find it. It is captioned "British advance South of Caen", but more likely it shows Canadian T16's.
Who can come up with the real identity of the T16s in this picture? NAC number? Location, date or anything else?

Thanks,
Hanno
