ACA and MNT are both Canadian-based grading companies, but they've built genuinely different businesses. One grades sports cards exclusively out of Quebec; the other grades a broader mix of Pokémon and sports cards out of Ontario.
Here's an honest, practical comparison for a Canadian collector deciding between the two.
None of this requires prior grading experience with either company.
Understanding what each company actually accepts matters more here than with most grader comparisons.
If you're submitting Pokémon cards, ACA simply isn't an option — it grades sports cards exclusively. This single fact eliminates half the comparison for a lot of Canadian collectors before pricing or turnaround even enters the conversation.
For sports cards specifically, both companies are genuinely viable, which is where the rest of this comparison actually matters.
ACA rewards larger batches with a lower per-card rate on its regular turnaround, while MNT's pricing blends batch size and speed tier together across four turnaround options. Running your specific batch size and desired speed against both companies' published rates is the only reliable way to know which is actually cheaper for your submission.
Neither company's pricing is simple enough to compare from memory — pulling up both rate cards side by side avoids a costly guess.
Both companies return cards in a protective slab that benefits from the same downstream storage. EVORETRO's Graded Card Sleeves work with either brand's slab.

MNT has built a reputation for grading harshly, with standards described as comparable to BGS's strictness. ACA's evaluation process, which includes microscope and UV light examination, is also thorough but doesn't carry the same specific reputation for a tough numeric scale.
A collector chasing a specific high grade should factor this reputational difference into where they submit a genuinely strong card.
MNT publishes four clear speed tiers from 2 days up to 3 months. ACA's regular turnaround currently runs around three months, with Bronze, Silver, and Gold rush options bringing that down to 30, 10, or 3 business days respectively.
For a genuine deadline, both companies offer a fast-but-expensive option — comparing the actual rush-tier cost for your batch size is worth doing before assuming one is automatically faster or cheaper.
For Pokémon cards, MNT is the only option between the two. For sports cards, the decision comes down to running both companies' current pricing against your specific batch size and desired turnaround, since neither has a simple, universal price advantage.
There's no rule against using both companies for different parts of a mixed collection.
Both companies give collectors a way to confirm a slab is genuine after the fact. ACA logs every graded card in a searchable database on its own website, while MNT publishes a dedicated verification number lookup plus a population report tracking how many copies of a card exist at each grade.
Neither tool requires an account or a fee to use, which makes checking a secondhand purchase from either company a fast, low-effort step worth taking before paying. Bookmarking both tools ahead of time, rather than searching for them mid-negotiation, makes running the check practical at a card show or during a live online auction.
MNT's population report specifically becomes more useful the longer a card has been in circulation, since a thin population at a high grade signals genuine scarcity beyond what the grade number alone suggests. ACA's database serves a similar authenticity-confirmation purpose, though it's framed more around verifying a specific card than tracking grade-level population trends.
Checking either tool before buying a graded card, rather than trusting the seller's description alone, is a habit worth building regardless of which company graded the card.
No, ACA grades sports cards exclusively.
MNT has a reputation for grading harshly, comparable to BGS's standards.
It depends on your specific batch size and desired turnaround — run the numbers for both.
Yes, many collectors split submissions based on card type and turnaround needs.
