Service shops recommended by one or more 944/968 owners:
Refined Motorsports (North York)
Lloyds Autosport (Mississauga)
RSP Motorsport (London)
Response Engineering (Port Perry)
E U Autowerks (Vaughan)
I highly recommend G-Tek in East York for 924, 944 and 968 service. A number of UCR members go there for service and Tech Inspections. They are very knowledgeable and have all the required special tools and test equipment.
