Clay bricks can last several hundred years. Precast exterior panels will last at most 50 years. Brick weighs 5 pounds. A precast panel is around 5 tons. Many more options with damaged brick as well. It can be reversed or replaced with brick forming the inner layer ( for solid brick walls) .
The only option is to recreate which isn't preservation. Costly as well for something that isn't too popular.
Though judging from what I figured through the Simpson Tower thread, you're generally pretty unversed, disinterested, and amateurishly ignorant t/w Toronto's architectural history (and not just that of the recent past) as it stands. (And this is less apropos *this* particular example, than of your implicit write-off in toto of precast panelling a la the 1960s.)
Besides, I get a whiff of this from your argument...

The teardown craze in Forest Hill began roughly around the time that North and South Rosedale became Heritage Conservation Districts. These designations came about due to protectionist residents committed to defending the neighbourhood’s “clearly discernible character as a picturesque suburb with varied architectural styles” (as stated in the group’s heritage guidelines). It’s now next to impossible to build a new house in Rosedale, unless you’re willing to spend tens of thousands of dollars at the OMB. Real estate agents and builders actively discourage their clients from buying there. As a result, anyone looking to build a new home in a wealthy neighbourhood close to downtown heads west. Over the past decade, 171 new homes have been built in Forest Hill; in Rosedale, 38. One high-end Toronto builder tells me Rosedale’s historical designations have backfired, particularly in North Rosedale. “The guidelines aren’t creating better streetscapes. They’re saving a lot of houses that aren’t worth saving.”
Yeah, I get the picture: to a certain mentality, those "aren't worth saving" houses are obsolete albatrosses just like 60s precast panelling. And just like maestro seeks to play off "recreation ain't preservation", those who decry HCDs gripe hyperbolically about not being able to do nuthin' with their houses, y'can't even bring them up to code, replace knob & tube wiring or make the place post-Y2K *livable* without leaping a whole lot of pesty "protectionist" hurdles, bla bla etc etc. And even if you *could*, it's still, uh, costly for something "that isn't too popular"--at least, among a certain class of agents and builders and clients...
