This is a good start, but 45 minutes is obviously too long a wait for certain applications, and just fine for others. There are many times when you decide you're going to leave at pretty much exactly the time you leave.

One could build a system to do it better, but there are inherent limits since you obviously want multiple people on the shuttles. A jitney service may make more sense though might not be quite as efficient.

Of course, in some cities, you can wait 45 minutes for a cab. Due to bizarre regulations, the taxi companies in San Francisco can not guarantee you will get a cab. They are required to treat the drivers as independent contractors and though they might call a driver to come to your house, the driver is allowed to bug off and you can't do anything about it, as you have no contract with anybody until you get into the cab.

Oakville of course is very suburban. I know, I grew up in Clarkson.
