In practice it's quite different. For example if you send money to a suspected terror group your bank will block the transaction and freeze the funds (that is, they don't even get you your money back), even in the absence of any crime.

They won't do this for regular criminals. Even if they know that a transaction is probably related to criminal activity, the bank will just file a report and complete the transaction. Except for terrorism financing and sanctions evasion, it is entirely the job of Law Enforcement to act on reports.

I desperately wish that were true, but alas, that has not been been the case for several decades. It's cool to indefinitely detain and torture suspected terrorists, haven't you heard? Folks didn't care when it was just Muslims, but we all lost our rights to the war on terror.

Bill C-51 was written to enable the government to silence dissent. That's a right we all need. But it was passed at the height of the Idle No More protests, which many of the truckers out there would be vehemently opposed to. Politicians gain power when they can use fear and hate to fuel divisions and justify the erosion of our rights.

Unless you're specifically paying someone to engage in arson and murder, which isn't the case, it's not illegal. Funding terrorists is illegal in a way that funding someone who happens to be a felon isn't.
