I'll give it best. I'm not a regulatory lawyer; however, I'm familiar with many of the proceedings.

Yes - In Canada Incumbent Cable and Telephone companies are mandated to provide third party wholesale access to their infrastructure.

The two ways you listed were related specifically to the provision of Static IP addresses. Traditionally ISP's utilizing TPIA have only had access to dynmaic addresses. This is because the incumbent runs the DHCP server the the cable modem utilizes. The third party ISP needs to provide blocks of IP addresses to the incumbent who in turn provision that in their DHCP servers and their network. The third party ISP cannot control which address gets assigned to which customer.
I believe John was trying to highlight Paragraphs 14-19 of http://www.crtc.gc.ca/eng/archive/2012/2012-96.htm that talk a bit about how the CRTC sees its role in Internet number resources.

I believe that related to the Static IP address issue. The policy here is trying to deal with overall IP addressing for TPIA customers

If by "rigged" you mean "designed" then that is a rough view of one problem faced by TPIA providers.
There is also the problem with the incumbent growing. Many cable providers utilize node splitting and other techniques to get higher and higher speeds. As they break up their network the third party ISP is affected too as the number of places that addresses need to be placed increases.
