I did not say that lasers cannot cause damage to sensors. I'm aware of that possibility and have been for some time.
Go back and read what I wrote again and why THIS particular example is almost certainly not caused by that. It is important to the OP to understand that.
The specific image issues on THIS camera are more consistent with some kind of sensor-related problem.
(I now see that the OP has confirmed that the camera was not exposed to lasers when the problem began.)

That doesn't look like blown pixels to me. It looks like the sensor took a hit or was somehow damaged in the bright dot area that destroyed the entire vertical row.
Have you done any nightclub or concert shooting where perhaps it got hit by a laser?
Either way, it looks like you're going to have to have it replaced. Hopefully it won't cost a ridiculous amount. Good luck and let us know how you make out.
To our OP:
I’m thinking that the laser theory is extremely unlikely since the problem pixels all seem to be in the same physical column on the image. Aligning a laser that perfectly during a performance, especially while hand-holding the camera is not impossible, but it is about as close to impossible as you can get and not be there.
I think this also makes physical damage (for example by something striking the sensor surface) equally unlikely.
My bet is that this is a sensor issue, though that could include some kind of issue with the connections to the sensor in the camera. It is weird that it skips over pixels though — when I’ve seen stuff like that it is usually a whole row or half of a whole row.
Also, when I’ve seen issues caused by bad cards (or bad connections to cards) they have looked a whole lot different than this — often multiple horizontal lines (not vertical) and with odd patterns.
In any case, that camera is either going back to the seller (assuming that it arrived with this issue) or to Canon for warranty service. I would at least contact the seller and have a conversation about it — though if you have had the camera for a while without noticing it (even if because you did not use the camera much) it may be too late to say/do much about it.
Good luck and I hope you get it resolved.

Here's one of many reports of low wattage laser damaging sensors. Take special note of the damage pattern at 1:45
And another segment at 3:20 when he's talking to CPS about the damage.
And just for the record, I was simply tossing some ideas out there that might have explained how it could have happened, which seems to not be the case based on the OP's comments.
