What is the current state of the law in the United States and Canada on the doctrine of joint prosecution?

Further, at pp. 432-433, Lacourciere J.A. reviewed the important American judicial authorities on this subject, effectively concluding that the general well-established rule in the United States, is that “upon the trial of one charged with crime it is not permissible to show that another jointly or separately indicted for the same offence has been convicted or acquitted.” This principle continues to be applied in more recent American jurisprudence. See, for example, United States v. Woods, 764 F.3d 1242 (2014, 10th Cir.C.A.), at p. 1246; United States v. Cannon, 475 F.3d 1013 (2007, 8th Cir.C.A.), at pp. 1023-1024.
