That's a really good question.
It depends. It depends on what system you're talking about. If you're talking about going into the work system, then through the workforce development agreements there are a number of federal-provincial funded agencies that work. There are also some at a federal level through the opportunities fund that do direct services for work. With regard to navigability around support networks, it's a hodgepodge, and it depends on where people land.
When I sit on the CPPD round table, there are people with lived experience there, and they all talk about the struggles that they had to finally find an advocate who could help them navigate the system to get into CPPD. There isn't one that I know of.
