I was wondering if anyone might know where I can download the rectangular administrative boundaries shown in the image below. I have highlighted one of them in red. On the image, you can see that the naming convention consists of some sort of numeric administrative identifier, as well as a name for each area (which seems to correlate roughly to the nearest city or town of any significance).
I require the spatial file in order to provide a quote for a large project and I haven't been able to find anything. The only information the client has is in paper format. The title on the overview map shown below is Provincial Series and Crown Land Use Atlas Index - 1:100,000. I have searched the Provincial data available from LIO, the Federal data available at GeoGratis, and I've tried numerous Google searches with no luck.
Any assistance would be greatly appreciated as I'd like to avoid digitizing if possible. Thanks in advance, and here's the image:
