Lie Groups and Lie Algebras, chapter IX, § 2. Maximal tori of compact Lie groups
Every integral subgroup H of G such that rk H = rk G is closed: indeed, the preceding proof shows that H is the identity component of its normalizer, which is a closed subgroup of G.
Bourbaki sets the proof directly after the statement, and the corpus does not separate them, so what is above is the statement and its proof together.
