Hello Petemj,
I'm sorry to hear you're disappointed finding out your phone does not have that particular function.
It's not uncommon for phone models to have various versions for the different target markets. Some potential differences between the versions might include different processors, varying bands/frequencies, dual-SIM offerings, etc.
As far as I can tell, the Canadian version of the Huawei Nova Plus is the MLA-L03 (see here). You can view some of the differences on specification websites like GSMArena. However, those sites can often provide generalised specifications and may not accurately represent differences between the versions (unless specified like bands/frequencies).
Your best option in determining the specifications of a particular model version is to search for the specific model number. You can then search for the specifications for that version. I try to find the Canadian version model number from the company's Canadian website first. Often, they will also provide the proper specifications. However, some do not. I then suggest searching and comparing the specifications for that model number from multiple different sites. If I can't find what I'm looking for, I would then start asking questions -- either from the company itself or a relevant forum. Does <model version number> have ____?
If I can't seem to find the model version number on their Canadian website, a good place to start is to Google: What is the model number of Canadian version of ___?
Hope this helps 
Cheers
