Last week was the annual Ontario Fruit & Vegetable Convention held at Brock University in St. Catharines. It's a big thing, with about 1200 people attending. Seven workshop sessions run concurrently throughout each of the 2 days on many topics, so there's lots to choose from. There is a trade show with around 150 exhibitors representing farm equipment & products, nurseries, farm organizations ... It's a great 2 days!
One of the most useful sessions for me concerned high tunnels (or hoophouse or unheated greenhouses). Here's a picture of ours at Thiessen Farms.
