The Current Reality
A 1215.5 metre main runway and two 309 metre
Marine Exclusion Zones (MEZs).

Porter Airlines has presented two illustrations of its airportexpansion plan to the public.

The Globe and Mail's original infographic did not showthe extent of the filling required.

It was subsequently revised to show required apronsbut still not the necessary taxiways.

Future Transport Canada Requirement
150 metre Runway Exit Safety Areas (RESAs) at the ends of such runways.
7/28/2019 Analysis of Impacts from Porter Plans
11/56
NOTE: Porter expansion + Transport Canada RESAs together fitinside the current MEZs. So Porter states:
" The amount of lake that all of Toronto enjoys today
will remain the same." Porterplans.com
But the logic of MEZs remains,
and if the landmass moves outward, so must the MEZs.

Most Conservative Interpretation
The MEZs move out by the extent of the runway addition.

The MEZs move out by the total degree of the expansion.

Another Scenario: Westward Expansion
Since development of the Eastern portlands
would be hampered by jet overflights, expansion goes to the west only.
7/28/2019 Analysis of Impacts from Porter Plans
16/56
Navigation through the Western Gapwould be blocked.
NOTE: none of these scenarios enlarge MEZs for jets.
Consequences of the
Westward Expansion Scenario:
7/28/2019 Analysis of Impacts from Porter Plans
17/56
These scenarios posit:
1) that Transport Canada applies 150 meter RESAs to BBTCA
2) that the shorter 90 metre RESAs already at BBTCA canbe credited to the total RESA requirement
Short RESAs already exist

Expansion is sometimes depicted this way:

Whether at its current 1215.5 metrelength, or at its proposed 1551.5 length,
the BBTCA runway is shorter
than the 1800 metre Code 4 length.
But: BBTCA is not(and won't be) a Code 4 Runway

The needed
to accommodate this ambition would
be catastrophic to the waterfront.

A lot of the discussion of the CS-100
jets is abstract.
They , so theirnoise parameters are estimates.
But we can know very well what they willlook like and how large they will be.
Let's of theToronto waterfront.

Visualizing Things
Halfway across Toronto Harbour is about 1.2 km from
the usual touchdown point at BBTCA.

Ontario Place is also about 1.2 km from

That same distance from the Pearson runway touchdown point
is in the parking lot of an industrial unit.

Jets of the sort Porter wants typically approach at abouta 3 degree angle of descent.
And that's assuming no runway expansioninto the harbour.
That meansthe jets will be
about above the water.

At the end of the marine exclusion zoneyou are far closer to the BBTCA runway
than Pearson Airport allows people to approach,so I was not able to get a photo that close.

Regardless of noise profile,
SIZE ALONE
makes the CS-100 totally inappropriate in the
context of the Toronto waterfront.

In 1974 there were 5nesting pairs of Ring-billed Gulls in the NationalCapital Region, whereas now there are over 6000

Ring-billed Gull populations in the Lower GreatLakes region have increased approximately 12% per

If those jets and carriers were permitted at BBTCA,it would be hard to logically exclude smaller business jets.

Logically enough,
Porter Airlines would like to maintain
its at BBTCA.privileged position
That does not mean that
would not have strong claims
to the use
of this publicly owned and operated facility.

Other Considerations

Negative community impacts on the Toronto Waterfront
Negative environmental impacts
Improved rail transit to Pearson under construction
Waterfront Toronto's investment and positive payoff to date
City-side traffic congestion and parking
Losses of property values for waterfront residents
Challenges to General Aviation (ie: non-commercial)access to the BBTCA
among many others.
7/28/2019 Analysis of Impacts from Porter Plans
56/56
Porter Airlines has found an aircraft that is slightlythan the Q400s it currently flies from BBTCA.
But . . . the CS100 is very likely considerably than
other similar commercial jets.
Consequently, this aircraft represents a wonderfulopportunity for Toronto
an opportunity to make life for Toronto residentsliving in the region of Pearson Airport . . .
. . . NOTto make things for residents and usersof Toronto's waterfront!
