These ownership data, consolidated by Targeted.ca, can be tricky. Some insiders sell their positions but are not required to report it. Thus, you may see holdings that no longer exist. So I'd question any data older than two years. Also, there may be some double counting. In one case for example, Sprott Asset Management LP (the company) reports all its holdings, while in the same report there are two Sprott managed funds that individually report their holdings.

Nonetheless, this should give you pretty good idea of who's getting in and who's getting out.
