I agree it’s a good idea but we don’t enforce any sort of punishment.
On the GO right now, yet again an unplanned closure of exhibition station. I don’t understand how this is acceptable?

Alvin, you're softening in your old age! LOL No caning?

I've had that happen a few times with the soap.
No idea. I met someone at Union coming in on VIA.

Not really - I thought dropping them off at the end of the line on the last train of the night counter to the direction of their original trip might be more informative, but it might be a little too extra-judicial.

Maybe I am just blessed with a strong bladder, but I try very hard to never have to use the restroom on vehicles. Intercontinental flights are usually the only time it becomes necessary for me.

Yes. But only kinda.
The speed limit through that section is 95mph. There has been an additional PSO through the curves just to the west of that level crossing of 90mph for LRC and 75mph for everything else, so any non-stop trains generally aren't running the full speed limit over the crossing anyways - they're either braking for the PSO, or accelerating out of it.
On top of that, due to the proximity to Guildwood Station along with the Guildwood plant about a mile to the west, and the pretty stiff grade for westbounds, any local GOs aren't really doing track speed anyways. Yes, they will have to slow down, but the reality of the situation is that slowing down to 50mph while occupying the crossing is only costing them seconds on each trip, not minutes.
There are immediate plans afoot for work to reduce or remove the speed limit - cutting back brush along the ROW, along with some reshaping of the berms/ditches on either side of the level crossing to improve sightlines - but I am curious to see what they propose to the roadway changes to prevent this from continuing to be a problem.

"During prolonged periods of high heat, rail tracks have the potential to soften and expand that require us to run trains at slower speeds," the transit agency said in a news release issued Tuesday.

Is it too much to ask for retractable bollards with reactive armour?

I used to commute on VIA between Guelph & Toronto and we had to slow down for the same reason on super hot days. Kinda surprised (yet not), that we still haven't figured out how to fix this... 20 years later?
This just happened to my spouse on VIA the hot day last week.

It applies to all railway tracks, especially welded rail - at higher temperature metal expands, and if that expansion happens along a very long piece of rail, the accumulated stress can create a kink in the rail. The track is designed and built to minimise this, but when the temperature reaches the 30's in bright sun, the risk is greater and it makes sense to play it safe. Lower speeds mean the stresses imposed by the train on the rail (which add to the thermal stresses) are less.
There were plenty of track patrols out there yesterday and this will no doubt continue as long as the weather holds.

PS - it happens to other civil structures also - eg bridges are built with expansion joints as they expand and contract with temperature.

As Paul pointed out, this has been an issue for far, far longer than just 20 years. And the problem is that there is no real solution to it.
The actual problem is that our potential temperature range in this part of the world is just too great. Want to avoid slowdowns in the summer? The railways can increase the stressed temperature of the rails when they install them, but then instead you are going to have slowdowns in the winter when it gets really cold. And even more seriously, pull-aparts, when the rail suddenly fractures due to the cold.
Going back to jointed rail is not an option, either. For all of the headaches dealing with temperature swings, they pale in comparison with the amount of work necessary to deal with jointed rail - both in terms of the tracks themselves (checking bolts, checking gaps, falling joints, etc.), and the additional stress on the equipment itself.
The railways up here have decided that it is easier to deal with slowdowns on the hottest of days, so here we are.
