(abridged) We present an investigation of the clustering of i'AB<24.5galaxies in the redshift interval 0.2<z<1.2. Using 100,000 precise photometricredshifts in the four ultra-deep fields of the Canada-France Legacy Survey, weconstruct a set of volume-limited galaxy catalogues. We study the dependence ofthe amplitude and slope of the galaxy correlation function on absolute B-bandrest-frame luminosity, redshift and best-fitting spectral type. We find: 1. Thecomoving correlation length for all galaxies decreases steadily from z~0.3 toz~1. 2. At all redshifts and luminosities, galaxies with redder rest-framecolours have clustering amplitudes between two and three times higher thanbluer ones. 3. For bright red and blue galaxies, the clustering amplitude isinvariant with redshift. 4. At z~0.5, less luminous galaxies have higherclustering amplitudes of around 6 h-1 Mpc. 5. The relative bias betweengalaxies with red and blue rest-frame colours increases gradually towardsfainter absolute magnitudes. One of the principal implications of these resultsis that although the full galaxy population traces the underlying dark matterdistribution quite well (and is therefore quite weakly biased), redder, oldergalaxies have clustering lengths which are almost invariant with redshift, andby z~1 are quite strongly biased.
