Ask HN: Name a company in Canada with a name trademarked in the USA

I found a great name for my company, let's call it "XYZ Labs", and xyzlabs.com is available. However, xyz.com is taken by a company called "XYZ Software" which has the trademark in the US for "XYZ Software" under the description: "computer programs for use in computer networking, business, and education."

That seems pretty broad to me. I develop software which is used in education. But it's a completely different category of application than theirs. Also, I am in Canada, where XYZ is not trademarked at all, except as a beachwear company.

Am I safe to buy xyzlabs.com and do business as "XYZ Labs"? Or is this a bad idea?
