St Lawrence Market

I've been told the new Cafe at Adelaide & George is more furniture store than cafe.

The roof is starting to tarnish.

AI overview
Typical timeline

• 0-1 year: Bright, metallic orange/reddish-brown.
• 1-7 years: Darkens to deep brown (oxidation).
• 7-30+ years: The green patina (malachite/azurite) slowly forms as carbonates and sulfates build up, with coastal/industrial areas reaching this faster.

Factors influencing speed

• Moisture & Humidity: High moisture accelerates patina formation significantly.
• Pollution: Sulfur dioxide in industrial or urban areas speeds up the process.
• Salt Air: Coastal areas with salt spray age copper much faster.
• Climate: Warm, humid tropics accelerate it; cool, dry areas slow it down.
• Surface Orientation: Horizontal surfaces can weather differently than vertical ones.

How to speed it up

• Artificial Solutions: Mild acids and chemicals can create a pre-aged look in days, applied by experienced professionals.

Union Station roof is copper but brown so… 7 years old? EDIT Roof is 13 years old
Royal York roof age? EDIT some/all? 30+ years (possibly 1988-1993)

It does not appear they will try to keep the copper from turning green like it used to be. They would have to clean it and treat it the same day judging by how quickly it oxidizes. It’s also a very large roof to try and maintain that pretty sparkle.

The RBC reflection is very cool for lack of a better expression.

It seems to crank it up for The Southcore Financial Tower across the tracks, to the point of opposing shadows. (December 13th pic)
