I couldn't find precisely what I was looking for online (an answer to the question of month vs day vs year). For clarification, I went back to the letter my accountant had attached to my personal tax return, in which he states my entitlement to:
- an Ontario sales tax transition benefit for 2011 of $335 (expected in June 2011)
- a child tax benefit of $1532 for the period from July 2011 to June 2012. (I will need to update the spreadsheet to indicate a decrease of $25 per month.)
- the UCCB of $400 for 2011
