Does swimming pool water heater need to be protected with
GFCI breaker (50A)?
The heater(heat pump) is more than 10' from the pool.

Even if the code doesn't require a GFCI breaker, is it still worth the extra $100 for better protection?

IMHO, I would install GF protection. I don't have any CEC info for you.

An explanation of the benefits to the client, as opposed to the $$ for GF should help if the job costs are considered to be costly.

Well the heater leaks current and a class A gfci won't even hold if the heater is large enough. Class b GF protection does not protect life so how can it work for life protection except that class b can be used where class a is not available? Actually look at rule 68-068 especially subrule 7
So if the heater is within 3 meters and not the other side of a wall then yes GFCI protection is required. If the heater is further than 3 meters then no.
