The picture of the Browning seems to be of a Model 1907, or possible the Swedish military pistol that was a variation of that model Browning. Be advised that there are Colt pistols (Models of 1903 and 1908 "hammerless") that appear similar and are much more common. You're correct in assuming that their "prohibited" status limits their value in Canada. Instead of looking at GunBroker, which is American, look at some of the sites for Canadian gun sellers, to see what kind of prices they're expecting to get for similar pistols. But you really need to be sure what you have. And also, know that condition means a lot. If they look used, they'll bring in less than a gun that appears unused or very well cared for.
The picture of the Smith & Wesson is of a Model 59, a high capacity magazine gun. If it is that gun, it legally needs to have a magazine that has been limited to ten rounds. The Smith Model 39 and its variations, which are similar in appearance, but older models than the 59, has a curved grip backstrap, usually wood grips, a 4" barrel and a magazine capacity of less than ten rounds. Again, condition means a great deal in terms of value.
If you could post pictures of the guns it would help in trying to place a value on them. If the Smith is a Model 59, then probably $300 to $400, depending on appearance and function. The other gun is probably about the same. Take a look at the registration certificates. The guns should be identified there.
If you want to PM me with pictures, I'd be glad to help out more with them.
