In 1960, Foss became an honorary member of the Vintage Automobile Club of Montreal.
Also in 1960, Foss was awarded an honorary membership to the Antique Automobile Club of America as one of only two Canadians to have received this honour. The other is Colonel Robert Samuel McLaughlin who started the McLaughlin Motor Car Company in 1907 as one of the first major automobile manufacturers in Canada. The McLaughlin Motor Car Company ultimately evolved into General Motors of Canada.
In 1997 the City of Sherbrooke, Quebec unveiled a stone monument near the original site of his bicycle repair shop, to commemorate the 100th anniversary of the Fossmobile.
On December 28, 2020 the President of the National Association of Automobile Clubs of Canada (NAACC) released the following statement:
“I most certainly would like the NAACC to recognize this undertaking by issuing the Foss family, your grandfather and the ‘Tribute’ vehicle a formal written statement and presenting a certificate of recognition when the project is completed.”
