Q - different (and smaller, and more small farms) province, different options. There are weekend farmers' markets in the city and in most towns here. The biggest Halifax market is right downtown, and so is the one in Dartmouth. There's even a Saturday-Sunday market in the tiny village near me. Most flea markets (popular here) in the city and towns usually have people selling produce.

U-Picks are harder to arrange, nevertheless, there are lots of groups who specifically borrow or rent a vehicle for the purpose of taking people to U-Picks. It's a one hour drive to the Annapolis Valley from Halifax-Dartmouth. My elderly fixed-income neighbour went with one of these organized trips last weekend, coming back all happy and rosy-cheeked with bags of vegetables and apples and quinces and such.

You are experiencing the problem of size. Here, while chickens are illegal in the city proper, you could still take a Metro bus in several directions and pass a number of properties with small flocks of chickens.

Halifax also boasts a couple food co-ops. I was a member of two (at different times) when I lived in town, and they can be really good if they are run well. One of the things they do is buy produce in bulk direct from farmers.
