@StroomAfwaarts Far as I can infer from the video, seems to be Montreal
@joepie91 This is in Québec (province), 100% sure, french signs, with wording and usual stuff. Probably Montréal.
The left sign signals the “left lanes” that it can go straight through, or go left. Depending on the intersection, either it’s for protected turn, e.g. exclusive green, or it’s mandatory signal. Given it’s six lights, that looks like it would have “straight through” red/yellow/green, then “left” red/yellow/green arrows.
The lights on the right are signals for the rightmost lane(s). Given the obligation to go straight (green circle around arrow) “EXCEPTÉ AUTOBU” (except bus), the light then looks like it would be a red/yellow/*white bus signal/green light.
Buses have additional signals here, all white. Here it looks like it might be used to allow them to turn into a bus-only area.
Sometimes they are used to give priority go-ahead compared to the traffic, especially when they need to navigate through busy or complex intersections.
The last bit is the white-on-black signs. It’s a one-way, except for bicycles. When that signage is used, it’s often a previously two-way street that where one of the lanes has been removed, and replaced by two relatively wide cycle lanes. In my city they are generally on slower “local” roads, parallel to more busy roads.
The next sign up (white rombus and bicycle, with arrow) denotes a reserved lane. Since it's a bicycle, it's a bicycle lane. It could be "bus", "taxi", "n passengers", there are a couple variants of reserved lanes.
Then, hiding in the background is a fun one. Red circle crossing an octagon. This means "ABSOLUTELY NO STOPPING". There is text there, hard to say what it reads as.

I'll follow-up with more, and attachments :).
1. Red, stop.
2. Yellow, "it's about to go red, you have to stop if it's safe"
3. "round" green, which means go ahead any direction legal (e.g. no right turn here) Left turn is allowed on that one.
4. Green forward arrow means "You can only go straight forward"
5. White triangle means "only bus can go straight forward"
6. White angled line means "only bus can turn in that direction" here left.
Previous streetview dates show that the right light is the same for the four lights at the right.
Previously it was allowed to turn right, before they installed the new bike lanes. So the right set of lights would have likely had a right turn arrow for bus use.
Though now it is a single lane, so now it's just a second set of signals for redundancy.
@joepie91
looks like rainbow traffic lights, like rainbow zebra crossings
where is this?
