If you happen to be one of the eager people to grab the new VTA that was made available this week you may have to return it.
After being delayed 3 months (the original release date was supposed to be May 2007) the VTA contains an error and has been rescinded according to Nav Canada:
070923 CZYZ TORONTO FIR
CZYZ TORONTO VFR TML AREA CHART AIR 1900, 34TH EDITION, JUNE 2007
RESCINDED. CURRENT AUTH TORONTO VFR TML AREA CHART AIR 1900 IS
33RD EDITION, MARCH 2006
Although the charts never technically expire and you can fly with an old one, there have been some changes to Toronto’s Airspace that I know will be reflected on the new maps.
Thanks to David and Mark (see comments) for clearing things up for me.
