I know you asked about Quebec but I think it's useful to point out that blinking can mean wildly different things:
In Austria, a green traffic light will blink green four times before switching to yellow and red.
This is meant as a pre-warning to avoid people driving through "dark yellow". Austrian drivers know this and will usually stop at yellow (not red). They will also honk angrily at people who brake at blinking green. Drivers who don't know this Austrian specialty are thoroughly confused.
It's also worth mentioning that, in Austria, the duration of the yellow phase (before red) is always the same length -- opposed to for instance Denmark, where the yellow phase is much longer in complicated intersections because the traffic planners know that it takes longer to clear the intersection before the next traffic direction can start.
The green arrows mentioned in another answer exist in both Austria and Denmark; presumably throughout Europe. But even though many traffic signs have been standardized across Europe (or the EU, whatever) it is evident that many exceptions still exist. Standards... sigh.
(I'm from Denmark but live in Austria. I prefer the Danish method because it varies on a case-by-case basis, sometimes even depending on the time of day or on traffic sensors in the lanes.)
