From what I understand this should be quick.
Three big reasons for that;
1) The project is being split into multiple smaller contracts, and so some work can likely get started very quickly.
2) My understanding is that most of the design work was done in-house, meaning that there's limited design to do, but it will be moreso about the logistics and capabilities of the bidders.
3) The consortiums that will be bidding on this project are likely already largely known. Because we've been building LRTs now in the province for over a decade, we now have regular contractors who we will know have the qualifications to build them.
