It makes a big difference.
5 or 10 years from now won't be helpful to the OP, who I am assuming will need school in the next year or two, if not the fall.
I think it might have been longer than 10 years. Maybe closer to 12, but my memory is fuzzy and I can't find the original proposal date. The new housing around there started being built in 2003-2004ish, and Flemming was sold in I think 2005 or so, and the explosive growth in the BSD started shortly afterwards. So 2009ish makes sense. It opened to students in January 2021.
That's a person's entire public school career, time wise. Kids entering kindergarten now will probably never get to attend it, assuming it has similar timelines.
Also, just because land is set aside and/or acquired for this purpose doesn't mean it happens. Schools don't get built all the time, or on extraordinarily long timetables compared to what is proposed. Demographics change. Governments change. Unless it's actively being built, you can't rely on it ever getting built.
But I agree the building of Maryland Park was a gong show!
