I am in Ontario also, and have been ordering from Tootsi Impex. They offer a decent selection of organic, you need to navigate the site via the different brands to find it.
I have ordered organic grains, dried fruits, ginger, even pistachio butter. They have a fair selection. I believe it’s free delivery after $800.
For organic whole grains or flours, I order from K2 Milling, located in Bond Head, just north of Toronto.
For organic animal feeds (and we do consume their organic split peas) I order from Windy Field Farms located in Grand Valley- they do not deliver, but super nice people and great product.
There is also a co-op for organics- i believe its based in Mississauga, but the last time I checked you needed to have a group and have one persona act as the distribution hub for that group, not my thing. A quick search will find the name of the co-op if your interested!
I will be following this thread, it can be difficult to source some items here!
Cheers
