Can confirm, Canadian pipeline really helped me learn proper BG organization. Always mask in any FX layers to to your FG/MG/BG groups or overlapping objects so they can be easily turned on/off with all their treatments :,)
This is the biggest thing that shocked me moving from Canadian studios to LA studios. Lack of organization w/ background files.
Layers were all over the place with no consideration for the vendor studios and how they would need to use them –I'd often reorganize before painting.
