Would this be something covered under the canadian Dieselgate emissions warranty?
No, I don't think so. Not unless it the coolant leak is related to a part of the emissions system such as the EGR cooler.

systems:
- The entire exhaust after treatment system, including the Diesel
Oxidation Catalyst, the Diesel Particulate Filter, the Selective
Catalytic Reduction converter, the dosing injector and other Diesel
