Yes, absolutely.
When you go to military college, you have to complete four pillars: academics, military, physical fitness and bilingualism. A person has four or five years to become bilingual. Similarly, if someone fails the physical fitness test, they're given additional training support so they can improve. They get help.
For non-commissioned officers just starting out, yes, going to RMC Saint‑Jean is a shock. It's a lot to learn. They are taught certain things to become familiar with the language. It's not a test or a PO check. They won't need to say “bonjour” or “merci” in their second official language, but they're told that they're going to meet French-speaking and English-speaking troops. They may get a few sessions a week to familiarize them with the language; people will speak a bit of French or English to them, but they don't have to pass a test. That's one of the shocks they'll experience, like their first time in the gas hut.
