There are provisions that allow the minister to extend the timeline for up to 90 days in the various stages of assessment that you referred to.
In addition, if after having extended it for 90 days there were a desire for additional time for the review, the question would have to go to cabinet for decision. Such an extension of the timeline doesn't have a set number of days associated with it. They would identify what time frame was needed.
In terms of the specifics related to your question around the overall length of time of the review, the new timelines under the Impact Assessment Act are shorter than those under CEAA 2012. There's a takeaway presentation, which we have provided, that lays out the details of this, but grosso modo, there's the early planning phase, which is 180 days; then the review process itself under CEAA 2012 was 365 days. Under the new act It has now been amended to be 300 days. Similarly, the time for a review panel, which was 720 days, is now 600 days. Then the final decision step by the minister is either 30 days or, in the case of cabinet, 90 days.
In addition to those time frames, there are the potential extensions that you noted of 90 days, by the minister or by cabinet.
