Canada has ordered Google to censor searches world-wide.

The accusation against Datalink makes no sense to me. What is wrong with buying products and reselling them under another name? And "acquiring trade secrets" is not in general wrong — and whether it is illegal depends on how it is done. If it's done by taking them apart and examining them, that reverse engineering, which in general is lawful.

Be that as it may, to allow any country to impose global censorship for any reason is unacceptable.

Google pulled out of China to reject its censorship requirements, but that was long ago when it still had the motto, "Don't be evil." What will it do with Canada?

For internet search to be run by a company (Google, in this case) that does business globally makes it vulnerable to global censorship at the orders of any country. The overall lesson is: search engines must be run by organizations that do business only in one country so that they are safe from being sued in other countries.
