A few more piece of info, the website is wrong about the training time, according to CFFSE website the QL3 is ~78 training days, so close to 4 months.
After the QL3(DP1 or whatever it's called nowadays) you are likely to get posted to Ottawa, you can also request to stay in Kingston to be posted to the regiment.
The navy uniform is IMO more comfortable than the CADPAD, especially if all you do is sit at a desk doing computer related work, think of it as business attire. Also massive perk, you can grow a beard !!
There are no postings to ships anymore as that was for the Destroyers (last one was decommissioned 2 weeks ago), but Comm Rsch still go on ships for deployments.
