When we were there, even though the new bus stops at MK were under construction and not yet complete- AK was running a bus that went to MK directly (not by way of TTC), and then a separate bus that went to TTC. I'm positive of this because I needed to go to the TTC to hit the lost and found to check for a lanyard with pins that DD lost, and DD and DH took the other bus. Of course, that doesn't mean that there weren't some days during construction that they didn't run a direct MK bus, but I'm pretty sure now that construction is done there is always a direct bus.
