This change was supposed to take place January 2011, but was delayed for a year so that manufacturers could have time to make the changes they needed to make to all of their seats. Here is my blog from last year -- Canadian child car seats and what is happening in January 2011
This does not change the Ontario Laws.
The Ontario Law still states that:
Rear-facing until 20lbs (with a recommendation of 1 year of age)
Forward-facing in a 5pt harness until 40lbs and 40"
Booster seat until age 8 or 4'9" or 80lbs
Yep, that's it. All of those number are on the very low side in my opinion. But those are the laws in Ontario.
Please read my other posts to know more about rear-facing, forward facing and booster seats.
So what are these new regulations?
As stated on CTV News:
Forward-facing child car seats will have to accommodate children weighing up to 66 pounds, instead of the current 48 pounds.
An infant will be defined as someone weighing up to 22 pounds, up from the current 20 pounds.
How does this affect you and your child?
You do not need to get rid of your current seat. However, it cannot be resold (not that we recommend that anyway) because it may not abide by the new regulations.
There are many seats already on the market that meet the new regulations already. Britax and Diono are two manufacturers that have seats meeting the new standards. I'm sure there are others, but know these two off the top of my head.
