It depends on how heavy the contents are and how big the envelope is.
The amount of stamps needed for an envelope is determined by weight. Weigh your a4 envelope and you will know how much postage is needed.

I successfully mail CDs all the time with 2 stamps.
One 'first class' stamp will get an ordinary business envelope from any address in Canada to any other address in Canada.

You can use forever stamps on a letter to Canada. It is worth only 44 cents toward the cost. You must put additional postage on the envelope.

how many stamps for a 10.4 ounce envelope
You would have to use 2 stamps to get a small envelope from Florida to Canada. If you do not want to use stamps, you can take it to the post office and it will cost roughly 72 cents to mail it.
Depends all on the weight.
In a standard size envelope, as of June 2009, you need 75 cents in stamps to mail an envelope up to 1 ounce to Canada. You could use two 44 cent stamps (you would be paying too much) or you can buy 75 cents of stamps at a post office. You need an additional 25 cents worth of stamps for each additional ounce or fraction of an ounce. Letters over 3.5 ounces have different rates.
