Actually, they appear to be allowed, through basically the same
subtrefuge that allows them in the USA. For example, I have personally
worked with the Canadian LZW patent document, and it is an algorithm
patent in that it is a Bernstein mental process patent. I doubt I
could teach the algorithm to someone else without infringing the patent
(assuming I were to attempt it in a place where Canadian patents apply,
Or, let me be precise. I have worked with a document that purported to
be a Canadian patent; the algorithm it described was as far as I could
tell identical to LZW. The co-worker who obtained the document told me
it was obtained by requesting it by patent number from wherever one
then requested copies of Canadian patents. (This was a few years ago -
1997-01-01 and 2000-12-31 bracket the dates.)

I no longer have the patent number at ready hand. I can probably get
it, if you're interested.
