I wouldn't put too much worry into it. As far as I know, "Recommended for Assessment" simply means that your application has passed the initial minimum-requirements test, but it has not been looked at in more detail or assessed by the admissions committee yet. The admissions committee will then pass on their decision to the Faculty of Graduate and Postdoctoral Affairs, who will approve the decision (admitted, denied, or waitlisted), similar to a professor submitting your "unofficial" final marks to the Dean, who has to approve them before they become official.
Based off of previous years, it is around the week of, and following, the 17th that the bulk of acceptances are sent. This makes sense, as the midterm period is over and there is a bit of a lull in the semester, giving the admissions committee (profs) more time to look at applications. The first week of April usually signals the end of first round offers, until the beginning of May when the second round of rolling offers happens (again, in line with the academic schedule).
There's no reason to worry, but lots of reasons to be excited!
