For 2015, SA fall into two groups, slow-AOR/fast-SA or fast-AOR/slow-SA. However, the combined time Received to SA is standard for everyone with a week variability being standard, so 56 days to 70 days is typical.
CanadaPost is highly variable in their delivery times. Three to ten business days is their typical delivery times. There is also a small time lag between SA being given and SA being mailed (physical or electronic).
AOR2 are highly variable, if you receive them or not, so don't worry if you haven't gotten one. Instead, think about investing $5 for a copy of your case notes.
