Growing in Ontario

[AntiCatastrofik]

Hey everyone! As the thread states, I'm in Ontario Canada. Specifically Wingham. I'm on my 4th year growing hops. I received them from my mother in law, who doesn't remember what kind of hops they are. So I'm naming them, Backyard Hops lol. I digress. I realized late last year that I was trying to get a harvest from Bullshoots so this year I'm pruning them out, but as of yet, I haven't seen any shoots that are best for a harvest. I've read, and watched that you should start training on or around May 5th but I feel like that's a recommendation for growing hops in the southern US. What dates am I looking for here in Ontario? Seems like Youtube and google forgets all about Canada when researching this info.
