In any case it could be studied more, and the information released publicly. I have seen a lot of people discount it as cost-prohibitive without a concrete discussion of the costs (an example of Canadian negative bias toward novel infrastructure projects).
I think it was a mistake not to try this on Argyle Street in Halifax when it was being redone. Halifax is probably an ideal place for this kind of infrastructure, because it is around 0 a lot in winter.

Since the sidewalks in Vancouver don't even get plowed in the rare event of snow I think heated sidewalks would be the most monumental waste of money of all time.
Maintenance would be a nightmare too.
