If you look at the Constitution Act, 1867, sections 53 and 54, there is some prohibition with respect to money bills and taxation bills. For these bills to be introduced first in the House of Commons, these bills would then require royal recommendation. If you look at Standing Order 79, you will find this requirement respecting royal recommendation.
On a private member's bill, private members are not prohibited from introducing such bills. It's just that during the process, bills that require the spending of money will need royal recommendation.
It is very rare that such bills receive royal recommendation, but it could happen. It's just that the Speaker won't put the question at third reading.
