Ontario, Canada is building a bunch of BWRX-300 SMRs and don't really have a desire for a naval reactor programme:

Canada is currently looking at new submarines, and the final two candidates are both SSKs (and not nuclear SSNs):

As an Ontario resident I wish they chose to build more CANDUs (which, AIUI, they are planning to do as well) rather than SMRs: our grid is in more need of 'bulk power', and SMRs are better suited to small grids (like the Canadian Maritimes) or small sites (like in Poland: replacing previous smaller scale coal plants).
