This is in Canada. I'll be using double face plats with 1 side solid and the other open for the switch due to box fill calculations.
Does that look correct?
Also in regards to wiring the the lights due I use the black wire coming in and the black wire going out and add a short 4"+/- black wire and merit them all together than connect the end of the 4" black wire to the light or can I do away with the extra 4" wire? (black or white wires)
If the existing wire from the light socket will reach, then you may tie that directly to the other wires entering the connection box for the pot light. No extra 4 inch piece needed.

The Ontario code allows 7 conductors in a standard, single gang switch box.
Plus any grounds from NM cable.
As already noted, 2 gang boxes wouldn't normally be required!
All he needs is a 14/3 in and a 14/3 out for a total of six.
The red and blacks connect directly to the switch and as you say the white neutrals are wired together!
My current gang boxs are 12.6 for the fill. I used a fill calculator I go off the net.
2 for each conductor, (2-14/3 = 6 6*2 = 12) So 12 plus the switch, plus the merrit and I'm over 12.6. They are standard Iberville gang boxes from Home Depot on Rona.
You need the single gang boxes with the bulges on the sides. The bulges give added capacity.
Here it is. The 3 inch version has a fill cap of 18. The 2.5 inch version has fill cap of 16.
When I do the calculation #14 = 6 conductors = 12. PLUS 1.75 for cable clamp, 1 #14 device = 4, #14 equipment ground conductor = 2.
Total is 12 + 1.75 + 4 + 2 = 19.75.
There is nothing in my 1999 Ontario code for counting connectors. As a matter of fact is states "shall disregard any space occupied by lock nuts, bushings, box connectors or clamps". Only insulated conductor count so no count for grounds.
by my count
6 conductors, 2 for device adds up to 8 conductors.
Table 23 says you can have 10 #14 conductors in a 16 cubic inch box.
k, I will replace my double gang box with the larger 16 or 18 fill and all should be good.
Thanks
