It gets worse than just N-spec tyres. I know a fella that works for a small local car lot, specializing in "toys". He was telling me that they sourced a US Porsche on behalf of a customer and the local dealership (apparently owned and operated by Ali Baba and associates) charged $1200 for the inspection. Just having N-spec tyres wasn't good enough - it failed because three of the tyres were N0 and one was N1.
After hearing a few stories like this I would never try and import a Porsche. If I couldn't find what I wanted in Canada then I would just buy a different car.

Something like that should have been fixed before sending it to inspection. I'm not a fan of mixing front to back rubber but mixing just one corner? Hmmm?

Depends. If they were all put on new at the same time, same make and model, but one had a different N-spec, I wouldn't like being made to change it unless it required a change due to wear anyway.
