Obviously it takes some suspension of disbelief to take anything in that document seriously, but it suggests that the Senate and Governor General (both unelected) make up the new "Government of Canada", with no mention of the House (elected). It's pretty clear that the intention of the "offer" is to remove the duly elected government from the picture in the mistaken belief that the Senate and GG are of higher authority to the House.

As far as the petition for an early election goes, I agree I can't find it in the MoU. Perhaps it was reading between the lines and combining statements made outside the MoU with what was found within.
