Canadian federal government has much more power than US feds can ever imagine to have. The criminal law is entirely up to the Canadian Parliament, and this is highly unlikely to ever fly in US. Further more, the courts have held that Canadian federal government can spend its money any way it likes to influence provincial policy. While the US Supreme court has allowed some percentage of money to be tied to state legislation (viz 21 year drinking age), it has also struck down laws which forces states to take up new spending or lose all the earlier grant from federal government (viz Medicare expansion in Obamacare). Each US state maintains its own Constitution and individual Judiciary, while the Canadian Supreme Court sits on top of any case of controversy in Canada,

US is much more federal than Canada, except may be for legal fiction where each Canadian province has their own relation to Crown. While Canadian federal government cannot outright strike out a state law, they almost never have to, as the power of Canadian federal government are almost endless where it really matter viz. criminal law, tax and spending.
