You can find the ZCS-L on BMO's website, but you'd most likely hit the ZCS first, unless you knew the symbol in advance.

CAREFULLY do a Google search and every one of the first ten results will send you to the ZCS, not the latecomer.

As a notable guy in this forum, I'm surprised at your comment, and wonder at what "the current state" might mean, when the well-known one trades 160X the new kid on the block.
As I said, I've been collecting monthly distributions for three years. If that's not "the current state", I am baffled.
