I am also in Canada ( Ontario ) so kindergarten starts at 4 but the cut off is dec 31st so a lot of kids , like Tayden are 3 when they start.
I can't imagine that a kid would be almost 6 by the time they start school! What a shame to miss out on that window of opportunity when their minds are so open to learning.
Tayden is in a Montessori school this year and she also is reading books with 2-5 letter words and can print and spell a ton of stuff. I couldn't imagine her not being in school.
Good luck with finding something to stimulate her
