Many, if not most, built environments labeled accessible are never entirely so.
GO Transit, a public transportation system that serves the General Toronto Area, in regards to backlash from a man using a wheelchair who couldn't get off a train because the station wasn't fully accessible, advised him to contact GO beforehand to see if his station was accessible.
Seriously? A company can't be "fully committed to accessibility" if the people who need it can't access everything they need to; everything able bodied users can; if it creates extra steps for users who require accessibility like calling ahead first or making alternate, expensive plans if they need to go to a station that isn't accessible.
Partial accessibility is a common issue in Toronto, well, probably everywhere. The TTC streetcars, which are the only method of public transportation (unless you apply for the Wheel Trans service and order it in advance of a trip) for much of downtown, are completely inaccessible, although fortunately a new accessible light rail system is being built. Only some TTC subway stations have elevators. The washrooms in the vast majority of bars in the city are located in the basements, with no accessible alternative to the stairs.
I am aware that creating accessibility costs money, but there must be more to it than that, a wider social issue. The need for accessibility is bigger than you may think.
