Quoted from Oaken:False. Two recent studies have found young (under 5) to be at least just as transmissible as adults.
The evolving situation in my area reflects this. Daycares have recently re-opened in our City, and are already becoming an issue:

Sadly, our city (Ottawa), which has been doing very well until now, is seeing considerable upticks in cases overall, and we have gone from one of the lesser affected large(ish) (approx 1M population) communities in the Province of Ontario, to the current hotspot, in a matter of a week or two.
I'm still not sure why we are opening bars and indoor dining (my Arcade and adjoining restaurant/bar remain closed by choice despite the fact we are allowed to open, unless, or likely until, we get sent back to Phase 2...), when we don't even know how we're going to get the kids back to school safely (for all of us).
It has been two weeks since indoor dining and bars were re-opened in Stage 3, so our local and Provincial numbers don't even reflect the wider opening of the economy, though it no doubt will begin to have an impact on this weeks figures.
