"Google Brampton elevation"
Brings up a map with elevation wherever you pin the map. Have at it.
Also, Waterloo is not Cambridge and YYZ is not in Brampton.
Topographic map Brampton
800 feet elevation in the heart of town, gets up to 900 feet in the northern part of Brampton, 700 in the southern tip near Mississauga.
I see you tried to post the link, but your original post is truncated at that point for me. Does it display in your browser?
I thought in this case we were talking about height to the concord supercharger, not to anywhere in Brampton. To my surprise (based on teslafi) the supercharger is almost 47m higher elevation than YYZ. [Edit: now that I can click the link from your post, it would say 49m between those two locations, which I think is sufficient to consider the map and teslafi to be in agreement.]
On average, Waterloo and Cambridge have the same elevation according to Google. The data are most interesting from SC site to SC site as those are the drives we'll actually be doing.
