That sux. We have gatekeepers here, but luckily it's not impossible to get through and a lot easier than other places. Wait time and yourself is the main factors. It takes time to go through the whole process to get the letters and then the funding approval from the province (average, 2 years). I'm very lucky because I got six months shaved off the list. Why? Because I ran into and met the gatekeeper who saw that I was well adjusted living full-time. So, working on yourself is very important here.
Else where, I don't know what it's like. I've heard of some horror stories, like the ones in Ontario at Clarke Centre. I actually feel pretty lucky that the system here is what it is -- it could improve, but it also could be much, much worse or not be there at all. Almost all of the other provinces have cut out the programs, funding, or have made it very difficult to access.
