Working for me.
But just in case here it is:

Plus, I am still asking if it is even legal for a 3 year to be in a booster in Canada?
No, it's not legal for a 3yr old to be in a booster in Canada. Most provinces have 4 and 40lb laws, and those that don't have the requirement of using a seat properly - and the boosters are rated as 4 and 40lbs minimum.
As to the OP, you're asking us which kind of law breaking is better to do... since you already have the Husky and have been ok with using it up until now, given your ds's age, I'd continue to use it or look into a legal option of keeping your ds harnessed.
This has nothing to do with being a die hard keep my kid harnessed to 9 or 10 thing.
We're talking about a 3yr old, not a 6 yr old. Even a 5yr old I'd have no problems saying a booster would be appropriate if they fit well and could sit properly. But I don't care how mature your 3yr old is, I cannot imagine a 3yr old who at some point in time in a car ride wouldn't move out of position. 3yr olds do not belong in boosters. My dd is 3, and she sits "maturely" in her car seat - but she's harnessed. Might she sit still in a booster, I dunno and I'm not going to find out... but my prediction is she probably would the first few trips because it was new and she wanted to prove she was ok to ride in it. 3yr olds get antsy, they get mad and frustrated - and you can't always pick the time and location that these things are going to happen.
Your ds is best protected in a 5pt harness. I won't tell you to use an illegal seat, but I will tell you a booster for a 3yr old just isn't appropriate. And it's something I would tell any parent regardless of the situation. And really, even if you want to argue that it's legal for him to be in a booster,
legal does not equal safe!
I have to agree that I'm not sure why you asked given that it sounds like you've already made up your mind.
But that's my :twocents: for what it's worth.
