The home you inquire about is in the Glendale Unified School District. La Canada H.S. is not within this district - it is in the La Canada Unified school district. So, unfortunately this property will not work, if an absolute is to be at La Canada H.S..
A great website to use for schools is http://www.greatschools.org - here you can look up schools and districts and their boundaries and ratings. A great resource if you have kids in school still.
I would be more than willing to assist you in finding a place within the LCUSD, or elsewhere as you desire. Please contact me directly, and we can determine what other criteria you want considered. You will then have the most current listings emailed to you directly.
