Let's hear from the usual suspects at Toronto Transportation on why we can't have this on Toronto's walkways or roadways?

There is probably a city lawyer out there that says this may not be AODA compliant or a liability issue because it is not smooth concrete.
We already have all-brick sidewalks and roads in select locations.
There is no liability issue associated with this.

Toronto's never seen a penny it refused to pinch.
Let me just say from personal experience in the asphalt industry, it is very expensive to produce coloured asphalt. It's almost about 5x the cost of standard black asphalt. The additives required are not environmentally friendly, cost of sourcing the colouring addictive and the cost of laying down coloured asphalt comes from designating separate construction vehicles and production plants to maintain a consistent colour without contamination. Then there is the cleaning of production equipment after a project is finished..Not just bricks.
Toronto has to use paint on top of asphalt, instead of using coloured asphalt. The paint will wear away over time, in addition they make the surface more slippery.
It is used extensively in NL as a top-coat for bike paths. They tend to last a very long time because bikes are essentially like having no traffic at all (inconsequential loading). As I understand it, they use red as it is the cheapest colour to produce. It comes at a premium but it is probably done at sufficient scale that the premium is not so large as to make a dramatic impact on project cost. Unlike a BRT roadway, which I imagine would need to be built to higher load rating and would not last as long.Let me just say from personal experience in the asphalt industry, it is very expensive to produce coloured asphalt.

That is part of the equation for the cost. Sourcing the material is the predominant driver of the cost. For example red pigmentation is created from adding iron oxide which happens to be only readily available from Germany. So the cost of transporting the material is much less to the Netherlands from Germany than to Canada (the VIVA project had to ship a lot of the red stuff from Germany for part of the project).It is used extensively in NL as a top-coat for bike paths.

I suspect our winters would be harder on them than NL would see--though they do get snow.
