100k and career over.

I'm pretty sure that State Boards have limits that are quite small, like $500 or $1000. The example given above was in Canada, and they might treat it differently. The real punishment is suspending your license and putting a stink on your reputation. Beyond that, if you're negligent, you can be sued and the limits there are only as far as a lawyer can dream.
The state boards are considered quasi-judicial, and the legislatures don't want to give them too much power.

Lawsuits aside I think the only repercussion the lead engineer for the FIU bridge disaster faced from Florida's board was not being able to renew his license in that state.

The Mount Polley example is the exception rather than the rule; most punishments are mandatory training, name and shame, temporary loss of license. Slap on the wrist essentially. Even the name and shame has gone away - most disciplinary cases are now published with the names removed / obfusucated.

No where in the same ballpark with...
$455,000,000.
