You have some options. Although it is suprising that no fish farms in Ontario have good supplies of YP for pond stocking. Sounds like a need that could be filled. For raising YP without pellets, the first thing to do is get a good forage minnow-shiner base established. I'm not sure what minnows are available from fish farms in Ontario. If you can research that and then provide that information, then we can better serve you. Check your local bait dealers and see what species of minnows they commonly sell to anglers. If you can find a local bait dealer or fishing camp that sells locally caught minnows that is a good start. Ask if they have "perch minnows". Among anglers "Perch minnows" are not actually small perch but small minnows used to catch perch. We can help you learn how to identify the best minnows for reproducing in your pond to raise YP. A last option is to trap some local minnows your self, learn how to identify the common ones and put some of the best ones in your pond. I often do this to get minnows not sold by fish farms. 30-50 of the correct minnows per acre can produce thousands of minnows over the summmer for a fall stocking of YP. As a last resort, YP can be obtained from a local lake in the spring before they spawn and are easily recognizable and male & female. A total of 10-20 adult YP can produce thousands of small YP from one spawning-hatching.
Since you are in Ontario walleye would probably work good as predators for your YP. I do that in my ponds and several others nearby. SMB can also work okay as predators with YP.
There is quite a bit of reading here about growing perch in ponds. Below are a few links to talk about YP.
You can pellet train your own YP if you live at the pond - I do this regually.
