Egads, sorry guys, I am waaay behind in catching up on some of these threads! We have all kinds of agility equipment, much of which is easily made. Weave poles with PVC (thin) and long screws to stick in the ground, and little PVC jumps that are built like horse jumps with cups that you can raise them (although we keep them low for Shelties). We also have an adjustable tire jump. All that stuff I got on ebay, believe it or not! Search "dog agility equipment" and you'll be amazed at what you can find pretty cheaply. Then we made a coop from two planks, and a dog walk also from two by fours. It's really pretty easy, and doesn't take up much space. We have a tunnel that I ordered from JC Penny -- it's a kids' toy and works wonderfully! The jumps you can put around the house in the winter and just run them there, although outside is better of course. But in Canada, Barb, I imagine you'd have a tough time finding them in the snow!
Anyway that's my information...not very helpful, but I'd suggest an ebay visit. Hope it helps!
