I did a bunch of research on bike trailers, and decided on the Croozer brand. They make a large one and a mini. The mini is perfect for 2 little ones, but not much else.
DoggyRide, Solvit and Instep were also high on my list, but I had a hard time finding anyone who stocked one and/or could ship to Canada, so I ended up with Croozer which I could find locally. There are a number of ones made for kids that could easily be used for dogs, too. I just found them too big for what I needed.
