BRAT can and does sometimes arrange transport runs up to Canada. And occasionally there are Canadian B's listed, too! I think what is most important is fit, so if you are the perfect fit for a Basenji in the nearby States, they'll find some way to get him/her to you. There's no harm in filling out an application with BRAT and seeing what happens. If Titan doesn't work out, there are always more in the pipelines, and it seems there are many more out East, near Toronto, than, say, my area.
You have many options, especially if you're open to rescue. Good luck!
