I concur with all above, the Ilford Delta films all are souped in standard B&W developers-not C41. This is 100% correct.
Most of the remaining labs, especially ones that do black & white, know each other. Here's an idea. Email Panda Photo Lab in Seattle. I bet they could suggest a lab in BC. Or you could mail order to them or any other professional lab. Remember that good pro labs employ photographers who are passionate about photography and really good at all the darkroom stuff. Keeping the labs busy and open will help perpetuate the use of film and is, therefore, good for everybody all around.
Whoa, you're right! The Ilford web site IS down. I was just there the other day so I'm sure it'll be back online soon.
