From the NP:
"Rob Ford so weakened by cancer treatments he’s unable to take the stairs after voting in advance poll"
"He said he is returning for another round of chemotherapy on Oct. 29 _ two days after the election."
eta - The second part about doing more chemo, I think he's wrong (again)
Interesting... going down stairs is usually harder, and he did that with vigor.
If there is a third called for then it would after an eighteen day clean-out.
