Just checked again on the Winchester Canadian dealer site as a double check and both the 44Mag and the 45Colt show as "on order" which means they are not currently available for us to order in Canada. They may have been in stock somewhere from a previous shipment but currently they would be a special order item.

Probably from previous shipments then.
I can name the retailers if you want to verify, but won't here without your permission.
Earlier when I posted, there were two 45Colts, one 44 Mag and two 357 Mags for sale.
As of this writing:
Retailer A still lists the 44Mag, but now it's marked "sold"
Retailer B has two 45 Colts in stock
Retailer C has two 357 Mags in stock
