What works for print pricing will vary depending on the local market.
What the market can charge in NYC, or Tucson, or Des Moines, likely won't be the same where you are there in Canada, because the cost of doing business varies in each city.
So, your pricing has to be based on your cost-of-doing-business (CODB) and your cost-of-goods-sold (COGS), or you take the chance you won't be in business long.
Looking at the prices that other photographers in your area are using, and basing your pricing scheme off of the averages could be a quick way to go broke, because their costs may be lower than yours, or they all looked at the prices that other photographers in your area are using, and based their pricing scheme off of the averages.
Another scenario is your CODB is lower than average, giving you a advantage you can use to increase your share of the local market.
