The thing with growing seeds like that from a random seller in Canada, or anywhere really where citrus don't grow naturally is it could be anything. You will wait years to see results and if it's not what was claimed you wasted time and can't even leave feedback. Pictures and reviews don't mean much unless there are results in the reviews and with many citrus plants looking similar there's no way of knowning those seedlings are the correct variety. To give a postive example, I've ordered makrut seeds which were easy enough to identify once the leaves grew out and were identical to what a makrut should be.
