The horizon is getting close.
Nonsense. TFC[itation] claims in the headline that "Ontario set to begin construction of Canada's 1st mini nuclear power plant" but then goes on to say "Premier Doug Ford's government has given Ontario Power Generation the green light to start construction on Canada's first small modular reactor". These two statements are not equivalent. "Set to begin" implies readiness, which is not the case. They were not just waiting for the go-ahead to turn shovels. You can see this is true because of the subhead "OPG to finance construction through cash, debt" which says they have not even financed the operation yet.
This is not the first time someone has gotten the go-ahead to build a SMR. NuScale got type approval for their design, but then they decided not to bother building it because they decided it wouldn't be financially viable because there were not enough potential customers. Your own citation also states that the SMR project would produce "3,700 jobs per year" which is frankly horrific for a project which is supposed to make nuclear cheaper.
Will they build this reactor? I'd bet no. If they do, will they meet their budget? No reactor has, as again, a quote in your own citation points out. Also, if they do build it, will it usher in a new age of SMRs? No, they will still be the most expensive source of power around, so it certainly will not. In fact they will raise costs, because there are unavoidable per-unit costs both in construction and decommissioning. In fact, increasing the number of reactors only increases the chance of a costly failure.
