I'm not sure if they ship to Canada, but I got a few to try in my zone 4a food forest from Reeseville Ridge Nursery.  They are pretty affordable so it doesn't hurt to try.  Here's the persimmon text from their website:

Diospyros virginiana E USA                           Persimmon
Medium height tree, much taller than wide. Interesting scale-like bark, edible plum sized fruit borne along the stems. Zone 4. Plugs 3.00 6-12” $4.00

If you're growing from seed, it depends on where the seed source came from.  If the seeds are from South Carolina, chances are they won't make it, but if the seeds are from Connecticut you should be ok.  I grow them here in Burlington Ontario usda zone 6a and 6b and they do fine.   With cultivars, you can find some very hardy ones.  I believe the one in quebec previously mentioned claim to be very hardy.  Growing from seed is easy as long as you cold stratify for several months and give the tap root a deep pot to grow in at first.
