You don't want CGL. This is currency hedged and IMO completely invalidates the point of owning gold. There is CGL.C, unhedged, which is comparable to MNT.
I think MNT is much better than CGL.C. Just in fees alone, MNT has 0.35% and CGL has 0.50%. MNT also has much better daily volume and liquidity than CGL.C.
Considering fund size+liquidity, think MNT is the only game in town for 'pure gold bullion in CAD'.
