I doubt that they would last one winter here in Kanata.

Terra cotta flower pots that get left outside here over winter self  
destruct in one season.

Fired clay brick garden walls with brick copings don't last much longer.

Thinking about the flat terra cotta roof tiles a bit more... I suppose if  
the roof is steep enough so that any moisture runs off and drains away  
before the clay has a chance to get wet and/or dries out before the  
moisture has a chance to freeze, then maybe they'd be okay.
