Hi. The investment in a dogs food pays back by not needing to feed as much per meal and improved health. Fromm is a reputable manufacturer and their Gold line is reasonably priced. Their 4 star line is mostly grain free which is better, but some varieties are more costly. The company has never had a recall.
If you have Costco in Canada, their Kirkland brand dog food is very economical and I think a well rated food.
However, overall dogs are expensive. The vet well visits, vaccines, spay/neuter, and grooming costs (depending on the dog and if you groom yourself, including nail trims) add up quickly. Then add on a crate for training, leashes, collars, toys and puppy training classes (unless you are getting a trained service dog or know how to train) is on top of the other costs and does not include food and the unexpected visits because the puppy/dog is sick, ate something it shouldn’t have (for example my sisters puppy ate a roll packing tape and that was $700 vet visit without surgery).
And if you intend to keep your dog by your side 24/7 then you won’t need daycare or a dog walker, but if you want to go someplace alone or overnight you’ll have to make arrangements.
I suggest googling the cost of owning a dog and find out the cost for the breed you are considering, average life expectancy and common health issues. A dog is hopefully a long-term commitment, so think it through and please make sure you can afford all the costs and never feed grocery store brand foods like Beneful. Good luck!
