Hi Salena,
Do you have a co-packer lined up yet? If you're planning to move from retail to an industrial ingredient format, that's something a co-packer can help with-they usually have established supplier relationships and preferred ingredients. That can save you from getting too attached to specific ingredients in your R&D phase, only to find your co-packer isn't willing to stock them. Most won't want to bring in 10 new ingredients just for one product. You'll likely need to reformulate anyway, so it's useful to define the specs that really matter-like needing a 90% whey isolate instead of just any whey protein.
A helpful resource is Food in Canada's Buyers Guide-it has a section on ingredient suppliers with hundreds of listings. Like others have mentioned, distributors are a great place to start. Univar, Quadra, Caldic, BCI, Snowcap, Brenntag, Blendtek, Foodtec,
To save yourself time and frustration, consider hiring a food product development consultant-there are lots on YODL who can help you navigate sourcing and reformulation.
A few practical tips: expect to pay for samples and/or shipping, especially if you're a new customer. It helps to have your own FedEx or UPS number to speed things up. Always ask for specs first and only request samples if the documentation looks aligned with what you need-that alone will save you a bunch of time and money.
Also, try to attend a supplier tabletop show if you can. CIFST runs them in BC, Ontario, and Quebec, and they're a great way to discover ingredient suppliers. If you can't make it in person, check out the exhibitor list or show catalog. Bigger shows like IFT and SupplySide West will have floor maps and show directories.
Finally, when you're vetting suppliers, dig into their documentation. Do they clearly state RTE status? What about their micro specs and thresholds? Is there a full allergen matrix-not just what's in the product, but what's on the same line or in the facility? Is the country of origin listed transparently? This is where working with a food scientist or someone experienced in commercialization can really pay off. Check out BC Food and Bev's Growth Hub, there are some modules on commercialization.
I see that we have a meeting scheduled for later this week, happy to dig into this more with you!
