I apologize for my snide remark. Sorry

There are two kinds of crisis - real and fabricated. The BC Teacher shortage is a fabricated one. It is a product of a dispute between the BCTF and the BC Government.

I did go review the Stats at WorkBC and the Ministry. As someone who just moved back to BC after a few decades (no skin in the game) I did notice this:

1 - Classroom sizes were not unmanageable. Even while BC continues it's hiring campaign, children will still be taught with no problem. The schoolboards can resource load with new hires. 

2 - WorkBC projections are 19,000 by 2025  (not 22,000 by 2022)
But:
         - Teachers must retire at earliest date (+15,000)
         - BC economy expands at rate they expect (+4000)

Given who the new BC Government is, you can risk these numbers down further. People need to work longer (higher taxes & cost of living /lower quality of life) and economy will contract, not expand.
