Certain stores may not carry things, but if you ask, they can order for you at no extra charge.
Anyways, I am very positive about Ilford and its future. They seem to be doing the right things in order for film to be viable in this day and age. I'm actually starting to see little if any gap in price between Ilford and Kodak or Fuji. Ilford used to be slightly more expensive, but its prices have remained steady while the others have risen.
Also, Ilford is the only film company whose products are consistently available locally. All the pro shops carry the whole Ilford range (sometimes not SFX, but otherwise no issue) in 35mm and 120. Edmonton is a small market, so I'm guessing this is even better in places like Toronto or Vancouver or Montreal (yes, I know...many stores have closed, but there still is a decent amount from what I've seen).
Kodak and Fuji (except for Superia) are so inconsistent with their offerings. One shop is so all over the place. You'll find Fuji 400H in 35mm, but not Fuji 160S. On the other hand, they'll have Kodak Portra 160, but not 400 in 35mm. So if you want pro neg colour, you'd have to go Fuji for 400 ISO and Kodak for 160. Then you'll find the 160S in 120, but not 35mm or the Portra 400 in 120 but not 35mm. Then you'll find Neopan only in large format and Acros nowhere to be found. Ektar disappears for months, only to reappear at $3 more per roll. The other shops are more Kodak-centric, so you'll find a decent selection of the 3 Portras, Ektar, Tri-X, and Tmax, but Fuji? Good luck if you want something other than Velvia or Provia, you'll have to order and wait (but at least the cost per roll is cheaper than the inconsistent store which may or may not have what you need).
Kodak Gold is now rare to find. This is fine, because I was more of a Superia person myself, but I never was able to give Gold a fair shake because it has disappeared so suddenly. I managed to snag Gold 200 in 35mm 36 exp for over $10. Ridiculous, but for one roll of hard-to-find stuff (that I'd never order online in bulk anyways), it is ok as it'll probably be the last Gold 200 I'll use.
So, I still buy Fuji and Kodak (leaning more Fuji lately because of Kodak's situation) just for colour, but B&W? Not worth the hassle when you have a fantastic company that is committed long term to film. When I stop procrastinating and finally start doing my own B&W developing, the amount of C-41 I go through will probably drop drastically.
