Power to Switch, then light, then into new room?


I'm in Canada and looking to complete an electrical rough in prior to drywalling. I've been searching for the correct way to wire (what seems like) a fairly simple setup, but can't seem to find anything to confirm my plan. Here's what I want to do:

- Run a single 14/2 wire from the breaker and into a switch
- Run a single wire** from the switch up into a ceiling box for a light
- Run a single 14/2 wire out of that ceiling light box into an adjacent room and into a switch
- Run a single wire** from that switch up into a ceiling box for a light
- Run a single 14/2 wire out of that ceiling light box into an outlet that is always live


I'm using the Electrical Code Simplified book and, on page 68, there's an image that seems to cover this, but I'm not 100% certain (Am I allowed to attach that here? Or is there a copyright issue?). This image shows power entering the switch on 14/2, then it goes up to the light box using 14/3 and then 14/2 goes from the light box to another light that has a pull chain on it. From this, I'm lead to believe that the 14/3 wire is used here to allow the light with the pull chain to operate independently of the switch (meaning this method allows continuous power to the pull chain light). If I'm correct, does this mean this is a good method to do what I'm trying to do?

Essentially, I'm asking if the wire denoted as ** above could be 14/3 wire.

Hope that makes sense and thanks for your time!

What you propose, with ** being 14/3, will work properly and meet CEC/OESC.

Not a bad idea to use deep metal or plastic boxes for the switches. If there's a
chance of a ceiling fan being installed now/later at the light locations, use fan
approved boxes/octagons.

Yes, use 14-3 between switch and light so you have both constant and switched power at the light. A better way is to go from switch to switch directly with 14-2. Still use 14-3 from switch to light so a ceiling fan & light is possible(as mentioned). Use a fan rated box either way as required in the USA.
