 There are 2 standard organizations regulating the WIFI radio systems in Canada.
-The actual radio regulations are the responsibility of the Canadian Government, found on the Internet at https://www.canada.ca/en/health-canada/services/health-risks-safety/radiation/everyday-things-emit-radiation/wi-fi.html

-The technical specifications for the equipment sold for WIFI service are produced by the IEEE and are found at  802.11 standards. WIFI is a trademark owned by the Wi-Fi Alliance, a USA industry group dedicated to certifying that WIFI products meet the standards. The names of the products were rebranded recently from the IEEE's  802.11 series to WIFI 4, 5 and, new in 2019, WIFI 6.

-Radio networks can be tricky to design and install in library buildings because the signals can be blocked by building walls, columns, floors and ceilings and bookshelves. Use a dealer with network discovery and testing capability (often an application on a cell phone nowadays) to design and purchase your WIFI capacity.  You are not delivering a home network for convenience so when buying WIFI equipment, remote management integrated with your data network and the ability to run through Power over Ethernet (PoE) are both important functions that should be on your list of requirements. This mostly rules out home consumer products.  New commercial Wireless Access Points (WAP's) are customizable with different aerials and mounting points , wireless mesh networks and are usually powered by PoE. These features allow you to place the devices to the best coverage points in your building with the fewest number of cables.

-New WIFI equipment using WIFI5 standards should offer at least two radio bands, a 2.4GHz band and a 5GHz band. The 2.4GHz band offers better range because it is more adept at penetrating walls and other structures. However, it doesn't offer the throughput and lower latency that you get with the 5GHz band radio. Three separate networks are often defined on these 2 bandwidths, (2 networks are defined on the 5GHz band) segregating the different patron groups from staff requirements perhaps.

-The latest Wi-Fi protocol, 802.11ax, is also known as Wi-Fi 6 or High Efficiency (HE) Wireless.  Wi-Fi 6 is designed to increase throughput to 9.6Gbps with less network congestion, greater client capacity and better range performance using improved wireless technologies.  This could include Orthogonal Frequency-Division Multiple Access (OFDMA) and Target Wake Time (TWT).  OFDMA improves overall throughput by breaking Wi-Fi channels into sub-channels, allowing up to 30 users to share a channel at the same time.

 Target Wake Time (TWT) is designed to reduce power consumption, extending battery life for mobile devices such as phones and tablets as well as devices such as security cameras and video doorbells that are often battery powered for home installation.
-No sooner will WIFI 6 be available in 2021 than another is on the horizon. WIFI 6E operates on a new 6-7 gHz radio band and is not certified for use in Canada as of 2020. It may be at least 3 to 5 years before product is available in Canada.
