WHO is suggesting that while reinfection, in the case of BA.2, is possible the risk is pretty low and previous infection of Omicron provides strong protection.

So Alberta having 45% of the population infected in a 3-month period would be pretty unbelievable.

Well I definitely can't tell you what the situation has been like but the reported cases in Alberta are publicly available and our CMOH has repeatedly stated that they believe testing is/was only capturing 1 in 10 positive cases. It is possible that estimate is wrong but from what we have been told by our experts the calculation works out to ~45%.
