I read in the paper the other day that a popular landmark for both nautical and aeronautical navigation will be no more on Monday.

“The Four Sisters” is an old electricity generating plant that has four big smoke stacks. The Toronto VTA shows the “four stacks” as a valid VFR reporting point. It’s been used for the past 40 years as such.

Here is the NOTAM restricting the airspace above the four stacks during the blasting period:

060427 CZYZ TORONTO FIR

CZYZ PURSUANT TO SECTION 5.1 OF THE AERONAUTICS ACT, AIRSPACE WITHIN

1 NM RADIUS CENTERED ON 433414N 793301W (FOUR STACKS) IS RESTRICTED

SFC TO 4000 FT MSL. EXC FOR EMERG MEDICAL/RESCUE ACFT, NO PERSON

SHALL OPR AN ACFT WITHIN THE AREA DESCRIBED UNLESS AUTH BY

AUTHORIZING AGENCY AT 416-891-2771

0606120930 TIL 0606121800

I wonder… Will they keep the same reporting point (and change the name?) or just remove it?
