The short answer to the second question is no, and anyone telling you otherwise is guessing. The useful answer to the first is below.
The cadence, by round type
| Round type | Rounds on record | Typical gap | Shortest | Longest |
|---|---|---|---|---|
| General | 178 | 13 days | 8 | 57 |
| Canadian Experience Class | 69 | 14 days | 13 | 29 |
| Provincial Nominee Program | 113 | 14 days | 13 | 28 |
| Category-based | 76 | 12 days | 1 | 27 |
Why the gap between shortest and longest matters
Look at the last two columns. The spread is the whole story: a rhythm that looks fortnightly on average has, in practice, included gaps of a few days and gaps of months. IRCC sets each round’s timing, size and category as a policy decision — when the department changes direction, the cadence changes with it, without notice.
That is why this site counts up from the last round rather than down to a predicted one, and why every odds figure here is phrased as history. A countdown timer would be a prediction with a clock face on it.
