Tu is placed after the conjugated verb (c’est-tu bon?). In composed tenses (like the passé composé), the tu is placed after the auxiliary, not the past participle (j’ai-tu fait ça?).
You are so awesome for providing tons of resources for those who want to learn Quebec French (such as myself). Thanks a bunch, it’s greatly appreciated!! 🙂
Second Lydia’s thanks…can you please tell us *why* ‘tu’ is used this way? It seems like an extra syllable for nothing!
It comes from the yes-no interrogative structure -t-il.
Il is frequently pronounced i, so -t-il can sound like -ti.
From there derives -tu.
