St Lawrence Seaway Management Corp.

The flag is white bearing in the centre a composite emblem, above a red maple leaf and at bottom a blue star separated by red-white-blue meandering stripes on which two black ships, of different types, sail towards the flag’s centre.

The symbolism is obvious – common Canadian and US interest in Great Lakes shipping – while the position of the national emblems simply indicates the geographical position of the two countries.

A flat image, accompanied by the name, is on the Oshawa Port Authority page:

Relevant information from greatlakes-seaway.com:

No house flag as such but hailing from the Great Lakes area nevertheless. On Boatnerd top row, third flag captioned as “Welland Canal.”

We find an explanation in the on-line book “The Flags of Canada” by Alistair B. Fraser, Chapter VII ‘Of Crowns, Councils, and Commissions’ [fra98].

Another major service offered to transportation in Canada is the St. Lawrence Seaway. The Authority places its 1962 logotype in white on a deep blue field (Note 9). The Seaway's main function, the lockage of ships, is represented by a ship in a lock all within a circle representing the Authority itself.

(Note 9) The St. Lawrence Seaway Authority symbol was created by Montréal artist and industrial designer, Gilles Robert. It was registered on June 6, 1962. [paraphrased by J. Mertens]
