Generally speaking, of course.
We're considering expatting to the great white north (2 kids in tow)
I have 2 kids, I receive CCB (Child Benefit) of $5000/year (reduced because of my household income). At lower income (in FIRE) I will receive $5000/child till they reach age 18. FIRE with kids is easier in Canada. I estimate my children will bring $140,000 to my bank account to offset daycare, sports and all other child costs.
In FIRE I have no health care costs, Canada provides certainty.
Education is similiar to State Universities. My Tuition was $6000/year circa 2000, my children will stay at home and attend my Alma Mater. Total direct University cost is under $30K for a 4 year degree. To save for school I will save $20K/child and the government will grant me a match of $4000.Then I'm done with University savings unless I choose to save more (I think I'll hit $25k/child, I'll have extra cash because of that CCB). That's 8-10 years of saving $2500/year, its pretty easy considering I can just use that CCB money.
Median Wage:
"The median total income of Canadian households rose from $63,457 in 2005 to $70,336 in 2015, a 10.8% increase." Statscan
"The U.S. Census Bureau reported in September 2017 that real median household income was $59,039 in 2016"
in USD the median CDN house earns $52,424 compared to $59k. THeres not a lot of difference in wages. in 2011 we were at parity, the median CDN household had higher income that year. Its not much different. Want to compare taxes? try comparing taxes between states first and then get
Overall, I think I've had it easier reaching FIRE in Canada than my doppelganger in the US. The big difference is that I think Canada is more generous towards kids and healthcare. To those without kids, the answer may be different.
