Well, your local restricted firearms dealer/s should be able to bring them in and pin them if needed, to comply with the law. Seeing as how assembled 30rd mags are illegal in Canada it is going be impossible to get them here for private use. If you were to try bringing mags across the border from the States, they would be seized. It is interesting enough that magazine parts are not prohibited, meaning it is legal to have the mag bodies, base plates, springs and followers as long as they are not assembled and could bring them back into Canada and vise versa..... I just got plain Labelle teflon mags with black followers, I am now looking into those Magpull products and swapping the springs...
