Henrys is one of the biggest retailers for photography LOL
Henry's - Canada's Digital Camera Centre - Photo Video Digital
there's one across the street from Downtown Camera
there is also Colourgenics, Vistex, Toronto Image Works,Northen Artist pro Lab (St Clair/Yonge), Korner Color Bay/Bloor (i don't know if they're around...anyone?), Aden (downtown location) not sure if Headshots does processing...anyone? ...man do i miss the "pink" house (Steinchen Lab)
There maybe some other independents in an around the GTA, one up Woodbine/Steeles forgot their name, pro lab if they're still around
There's also BGM ...wait i just checked...they're a full digital lab like Jones now but they're strictly commercial. Anyhow we have a lot of inhouse E-6, film (neg/pos) to choose from and you don't have to buy bulk you can get 1 roll, buy from the US and you pay shipping, their taxes and then our taxes plus their quantity...is it worth it to try a roll?
