Apparently the season isn't over! Karma Co-Op had a full basket of conventional ones from California yesterday. I bought the whole basket though (I juice them and freeze...great for cocktails and yucatecan food!). You could call and ask whether they will be receiving more.
The fruit guys downstairs at the South Building at St Lawrence Market had them a while ago, not sure if they still do. You can always try calling the Longos by the Air Canada Centre.

There is another thread here asking for these.... I saw them this week on Danforth Ave at the store previously called PAPE IGA. It's less than a 3 minute walk from Pape subway station.
