In Ontario, a private company partnered with VIA Rail, Canada's passenger rail company, for the Bike Train. http://www.biketrain.ca/
There are several train routes which originate from Toronto out in different directions to Niagara Falls area (wine country area, etc.), Montreal and up to North Bay, Ontario (which is over 1,000 kms. north of Toronto). Not sure what all the extras the company provides.
So cyclists as a tourist group, is being taken a bit seriously in some areas. Might take time. For the ignaural ride to North Bay, the mayor of that city met the cyclists.
Now, I recall when my dearie rode across Canada, he met a mayor of North Bay. This was 8 years ago. Guy actually gave him a lift for 100 kms., since bike wasn't functioning properly. Not sure if present mayor is the same guy.
