Last year, I was able to buy a SPEEDiagnostix kit for Canada on SPEEDiagnostix.com, but it seems it's no longer available. I may be missing something, but if it truly isn't offered anymore, it's unfortunate as I wanted to submit another test to continue building history for my car.

Are there any alternative options available in Canada?

I use WearCheck in Burlington. They're on my way to work so I just drop off my samples, but they support you sending in samples as well.

One cavet with these guys you need to explicity request that they do a Fuel Dilution trst or else they will skip it and report 0%.
