I've asked a few people with parking passes in Lot M if they know what is going on with the large scale construction project: no one had an inkling, thinking it was a just a repaving job.
I e-mailed the parking office April 16 to ask what was going on, and have not received a reply.
So today I was in the school bookstore on other business when I noticed a parking desk/kiosk in the store. I spoke with the person staffing the booth and asked about Lot M: they explained the work was a project for the Hamilton Conservation Authority (HCA) to protect the creek, and when I asked about loss of parking effecting current parking pass holders, they explained that drivers who had a permit in lot M and wanted renewal would get a spot on Lot P, right next to Lot M. They confirmed that no one currently in Lot M who wanted to renew would lose a space.
When I informed the person that there was no info on the parking web site, she immediately checked, confirmed it, and then contacted her supervisor to get something put up.
Hopefully news will get out about this excellent initiative by McMaster University, and that negative rumours of people losing parking spaces will be rebuffed by this win-win situation.
